The naughty pixies of Guernsey, the pouques, have been trying out the experiments

and have given some feedback. They have also asked other fairy folk around the

World to try them out as well. A hazard symbol has been put on experiments that will

need supervision by an adult for young children.


The fairy folk have thought

of a question to ask about

each experiment.

Use the question maker below

to think of another and ask an

adult to share it on twitter

using @GreatSciShare

You have to work out what is

happening in each experiment. Once you think you know then

Gran’mere will tell you.



These practicals have been written and tested by Year 8 students

for primary students. They completed them in their science lessons

during the first lockdown. The theme is Magic.

Some experiments require supervision, mainly due to heat being


When supervision is advised this sign appears:

Written in a text box under the sign is the

hazard for that experiment. The user is

responsible for checking safety of the experiments listed.

Young children should be encouraged to ask questions and design

their own experiments using knowledge about what they

have learnt. If you are unsure about a chemical to use,

then check the bottle as hazard symbols are always put

onto substances bought from shops.

Magic Multicoloured Milk

This experiment demonstrates a magical mixture and what happens

when colour moves by itself.


« Milk (whole, skimmed or semi-skimmed)

« Dinner plate

« Biodegradable Cotton buds

« Washing up liquid (for example ‘Fairy Liquid’)

« Food colouring


Pour the milk carefully into the dish, just enough so that it covers

the bottom.

Add a few drops of food colouring into the centre of the plate, the

more colours the better. Make sure they’re close together.

Put a drop of washing up liquid onto the end of clean cotton bud and

place the soapy end of the bud into the centre of the plate. Now



Hold the cotton bud there for 10-15 seconds

and watch as the food dye magically bursts

outwards like a firework display. The colours

should mix and swirl while you hold the bud in

the centre. If you want to, you can repeat this

experiment with different colours to see what happens.


Science explanation:

Warro! I am La Gran'mère du Chimquière and I am the

head of the fairy folk.

It is your turn now to be the teacher. Can you explain why

the food colouring moves when you touch the milk with

the detergent?

Click on for an answer.

Hi, I am a pouque from Guernsey and

my name is P’tite Jeanne.

I used very fresh creamy milk

straight from a Guernsey cow. It

worked really well! A good

explanation of the science bit.

It was also good that the equipment was something most people have

in their house.

My question is: Would this work if I used a piece of soap instead of

washing up liquid?

What is your question?


Magic Mentos.

This is a quick and magical explosion experiment.


2 packets of Mentos.

1 bottle of Coke.

A lot of space for when the bottle explodes making a sticky mess.


Open the bottle of coke, wait for all the bubbles in the coke bottle

to dissolve, then open the Mentos packet and put all the Mentos into

a bowl. Put one or two Mentos into the coke bottle, ( you must do

this very quickly as the coke fizzes up very quickly). Then leave the

bottle on a flat surface and watch it explode.

Results: the coke went flying into the air and then it slowly came

back down, and all the Mentos had mostly dissolved in the coke and

the coke was not fizzy once it came back to the ground.

Science explanation:

Warro! It is your turn now to be the teacher. Can you

explain why the mentos explodes out of the coke.

Click on for an answer.


Hi, I am Auntie of the starlight and I am the

Caribbean fairy godmother.

When I tried this out, the coke went flying up

and did slowly come back down, as mentioned. It

made quite a sticky mess so you should do it

outside. I think that this is a fun experiment for

all ages.

My question is: What other objects can you add instead of the

mentos which will also explode out of the coke?

What is your question?


Fairy Tornado

A fairy tornado is a mini tornado formed inside a jar

List of equipment:

- A slim sealable container or jar

- A teaspoon

- A ruler

- Enough water to fill majority of your sealable container or jar

- A teaspoon of vinegar (any type will do )

- A teaspoon of washing up liquid

- Glitter / Sequins


Firstly, fill your container up with water until it is 2cm from the top,

you can do this by measuring the gap your ruler.

Next add your glitter, or sequins, this step is totally optional.

Now measure out your teaspoon of washing up liquid and your

teaspoon of vinegar and pour them in,

feel free to stir if they are not mixing

into the water.

Add the lid to your container and

spin/shake your mixture in an upright

circular motion until you see a mini

tornado form after about 5 seconds.


Science explanation:

Warro! It is your turn now to be the teacher. Can you

explain why the tornado occurs?

Hi, I am an Älva fairy from Sweden

I liked the clear instructions and it

worked for me! The ingredients

were all in the kitchen, and it was

fun and interesting!

My question is: Will the tornado spin in the opposite direction if I

spin it the other way?

What is your question?


Self filling balloons!

The fairies are throwing a party to celebrate Queen Elgar’s 100 th

birthday, they are all so excited. Rose and Buttercup are the party

organisers, they have designed everything perfectly, except they may

not have realised how long it would take to blow up the balloons. So,

they had to use their fairy magic to make the process faster but they

need your help. Can you follow this top secret magic potion and help

them blow up the balloons before Queen Elgar’s 100 th birthday party?


» a hollow acorn (an empty bottle)

» Dragon tears (vinegar)

» ashes from the tallest oak tree (baking soda)

» a balloon


» start by putting 1/3 cup of oak ashes (baking soda) inside the

balloon (you can use a funnel to help you because it gets messy).

» Then put around 1 cup of dragons tears (vinegar) into a bottle.

» Place the balloon over the top of the hollow acorn (bottle)

» Then hold the balloon up so the oak ashes (baking soda) can fall

into the dragon’s tears (vinegar) below.

» The balloon should begin to inflate and the oak ashes (baking

soda) and the dragon’s tears (vinegar) should bubble up and go



Science explanation:

Warro! It is your turn now to be the teacher. Can you

explain where the gas has come from?

Click on for an answer.

Hi, I am a Leprechaun, and I am from Ireland.

It was fun trying this experiment. It worked

well and was not too messy. I filled the bottle

with too much liquid first and it came foaming

out before I had chance to put the balloon on

so don't add too much liquid.

My question is: If I add food colouring to the liquid, will the gas

blowing up the balloon be coloured?

Magical fairycakes

The ingredients which you will need are

55g butter

55g sugar


1 egg

55g flour plain flour (experiment 1) OR

55g self raising flour (experiment 2) OR

55g self raising flour plus half teaspoon bicarbonate of soda

(experiment 3)

-a couple drops of food coloring

-one drop of vanilla essence

First let me tell you of a magical story about how these fairy land

cakes first appeared. They were once spotted by the magical lake of

fortune by a science fairy who loved doing experiments. She took a

sample of this sweet-smelling object and spent nights and days

trying to figure out how to make it. Finally, after weeks of testing

she found the answer and made everyone in the village some. She

called her experiment a fairycake.

The fairy scientist wanted to know which ingredients made the best

fairy cake.


She did three experiments at the same time to compare the cakes.

1. She mixed all the ingredients

together in one bowl using plain

flour and put them in paper cases

and cooked them at 180 o C for 15


2. She mixed all the ingredients together in another bowl using

self-raising flour and put them in paper cases and cooked them

at 180 o C for 15 minutes

3. She mixed all the ingredients together in a third bowl using

plain flour and half a teaspoon of bicarbonate of soda and put

them in paper cases and cooked them at 180 o C for 15 minutes

You may need to ask an adult for help with the oven. Ask an adult to

take the cakes out when they are cooked as they will be hot.

These are the experiments which the fairy scientist narrowed down

for the best cakes.

The fluffiest cup cake was self raising flour. The other cakes were

heavy and didn't rise.


Science explanation:

Warro! It is your turn now to be the teacher. Can you

explain why only one of the cakes was light and fluffy?

Click on for an answer.

Hi, I am Trolde from Denmark and I love

cooking for my grandchildren troldes.

You can experiment with different cake

mixtures and add other things in as well.

Sometimes it won't make the cakes taste very

nice though! Use only small amounts of

ingredients just in case.

My question is: What will happen to the fairy cake if I make it with

bicarbonate of soda and add lemon juice to the mixture?

What is your question?


Bicarbonates Magical Concoction

One night in the forest, a group of witches were meeting secretly.

There were three of them, all crowding round the cauldron trying to

come up with a spell to turn their friend into a frog. One witch,

Bethany, had bought vinegar. The main witch, Sally, had bought

bicarbonate of soda. They started to mix the vinegar in the very

large cauldron. Bethany poured in the whole tub of bicarbonate of

soda! Huge mounds of airy bubbles sprayed from out of the cauldron!

A light brown goo covering everything for miles around. And to this

day, those witches have never, EVER, been found.


30 ml of malt vinegar

1 small tsp of bicarbonate of soda


1. Measure out the vinegar and pour into a container

approximately 10x larger.

Levitation potion

A long time ago some small elves were building their new houses.

They decided to build them in the trees, but they were too short to

be able to carry up their things. So, one clever elf decided they

should ask the friendly witches to

make a different potion for each

item, to allow their things to float

up the water pipes and into their

This activity will not only give you a quidditch field to play the game.


2 small hairdryers

1 (minimum) light ball(s) in varying sizes such as a table tennis ball

6 hoops or wire to use as goals

some card or paper for the field and stands

Optional: a marker to draw details on the balls eg: wings on the


The set up:

If you chose to make the field and stands then I would recommend

making them out of card.

For the field, first cut out your green card in an oval shape of your

desired pitch size then if you wanted to go into a lot of detail you

could get a pencil of a darker shade of green for the grass lines on

the pitch. For the white lines on the pitch, just use white paper and

for the sand at the edges of the pitch using your pitch as a template

cut out the yellow paper in that shape and stick everything down.

The stands are optional, if you want to do the stands then all you

need is some card the colour of the time of day you want, if you

chose to have black card then maybe change all the other details to


e darker as well. It might look like it is night-time in the sky and

day on the field otherwise, which probably has happened in that

wizarding world. Make your card the width of your pitch and the

height of your choosing. Also make some stands, I would print them

but if you wanted to, you could draw them.

To make the different types of balls, try to find different markers.

You could use some tinfoil rolled up if you don’t have anything else

and you could add blue tac to make the balls heavier.

How to play:

To have a match of quidditch set it up as above and chose which ball

to play with, chose the power setting on the hairdryer and go.

Alternatively, if you had more than two people with you then you

could get them to stand further away and to throw the balls. If

they hit the hairdryers then you lose 5 points.

For the next part of the experiment, you will need the 3 different

sizes of balls and a hairdryer.

Turn on your hairdryer to the highest setting and point it upwards.

Carefully place one of the balls in

the flow of air from the

hairdryer to make it float. Try

this with all the different sizes

and see if any are so light that

they float off or if any are too

heavy that they don’t fly at all.

To make this a bit more relevant

to quidditch, see if you can tilt the hairdryer enough to get the ball

into the opposing goal.


Science explanation:

Warro! It is your turn now to be the teacher. Why do the

balls stay up in the air with the hairdryer?

Hi, I am Draig from Cymru.

I likes this- but I can tell you that it

doesn't work if you breath fire on the balls!

My question is: If you only had one light table tennis ball- how might

you make it heavier?

Magic fairy bath bombs

One day lots of fairies started a magical and colourful experiment,

they called their product Bath Bombs.

For your mythical experiment you will need:

1. 1 ¼ cups of bicarbonate of soda

2. ½ a cup of citric acid (I used lime juice)

3. ¾ of a cup of Epsom salts

4. 1tsp of water

5. 3 tsp of essential oil (I used orange scented shower oil)

6. 3 tsp of olive oil

7. Food colouring (any colour you want)

8. Bowl

9. Wisk

10. Jar

11. Bath bomb mould

Here’s what you do to make your wonderful bath


1. Firstly place all your dry ingredients in a

bowl and whisk them up. Here’s a picture

of what mine looked like-


2. In a jar or a glass mix all the liquid

ingredients together (including the food

colouring) here’s what mine looked like-

3. Slowly – one teaspoon at a time

whisk your wet ingredients in with your

dry ingredients, this should form a small

but fizzy and magical explosion. Here’s

what mine looked like -

I had to add some more dry ingredients

to mine because it was too wet.

4. Now that your colourful ingredients are mixed in its time to

learn how time make your finished Magic fairy bath bombs…

a. Firstly squash your bath bomb mix into your moulds,

ensuring that all of your ingredients are tightly packed

into your mould. Make sure you work quickly with your

ingredients before they dry out.

b. Once your ingredients are in your moulds leave your

moulds on the side for 3 hours.

c. After 3 long hours. Place your bath bombs on a bit of

cling films and slowly but carefully tap them out of the


d. Then gently fold the cling film around them.

e. To make sure they stay in their beautiful shapes, push

the mould on top of the clingfilm (over your bath bombs).


This one is a fairy angel.

And you are finished- now you can have a nice relaxing bath, with a

wonderful sent and a fizzy explosion.

Piscantar Glacies- Ice Fishing

If you love winter, then this magical experiment is just

for you. You can have fun fishing for ice cubes no

matter the temperatures outside- all year long!


• Small paper cups or an ice cube tray

• Bowl of water

• String (yarn or kite sting works great)

• Salt


1. Fill the cup or tray up with water and place it in the freezer.

You can also use ice cubes from your freezer and skip this


2. When the water is frozen, remove the ice from the cup or


3. Put the ice in the glass or bowl of water. The cube will bob up

and down in the water and then float on the top.

4. Place one end of the string from the fishing pole on top of the

ice cube and sprinkle salt on the ice where the string is


5. After about 10 seconds, carefully lift the ice cube out of the

water with the fishing pole. You caught a fish (ice)!

Hi! I am Skyrgámur, the Skyr

gobbler Yule lad from Finland. I

come down from the mountains on

19 th December to steal all the Skyr

and give children presents.

This worked really well, and I

enjoyed it lots. I think that this is

the way Jack Frost fishes. Although he fishes for ice instead of fish

and he does this every Winter. You do have to use quite small pieces

of ice otherwise it’s too heavy for the string.

My question is: Will it make any difference if you use something else

instead of string?

Dodge the Giant!

Jack and the Beanstalk experiment

Jack has escaped the giant! But now he has a new dilemma. He must

climb down the beanstalk before the giant finds him! By changing

the gradient of the beanstalk, help Jack get down as fast as



A small toy person


A thin, straight, solid object such as a pencil or wire

A protractor

A timer/stopwatch


Tie the toy to the straight object using string, making sure it’s loose

enough for it to be able to slide down

Measure the gradient of the straight object using a protractor.

The Night of the Burning Jungle (Lucerna sub speculo)

A long time ago there were lots of jungle kingdoms on the planet. A

group of young explorers were using candles to see. When it was

time to rest for the night, they thought that they had put out the

candle by putting a glass on top, but someone knocked the glass off

whilst the candle was still hot. The candle relit, and burnt down the

jungle kingdom.




Drinking glass

Ceramic dinner plate



Place the candle on the plate. Light the candle and place the glass on

top of the lit candle. After a few seconds the candle will go out

Then try opening the glass when the candle goes nearly out. Lift the

glass slightly to see if the flame will relight.


Science explanation:

Warro! It is your turn now to be the teacher. How can the

candle relight?

Click on for an answer.

Hi I am a pouque from Guernsey. My

name is La Grande Mabelle.

You have to be quick with removing the jar again so

that the wick is still hot enough to relight. This also

shows how important it is to make sure that there is

no heat left in a candle when you put it out and walk away.

My question is: Does the size of the jar make a difference to the

time it takes to put the candle out?

Eritque arcus in speculo


You will need: water, a mug, 5 separate

cups, a table spoon, clear glass , skittles, hot

water and a pipette.



1.Separate the Skittles into the cups, in these amounts: 2 red, 4

orange, 6 yellow, 8 green, and 10 purple.

2.Heat a mug of water in the microwave for a minute and a half (or

long enough that the water is hot, but not boiling). Be careful

removing the water from the microwave–it’s hot!

3.Measure and pour two tablespoons of hot

water into each cup, on top of the Skittles.

4.Stir each cup carefully so no water splashes

out. The cups need to be cool for the next part

of the experiment, so leave them somewhere

where they won’t get knocked over. Stir them

every ten minutes or so until the colours from

the Skittles are dissolved and the water is room


5.Using the dropper, add the coloured water from the five cups to

the clear glass. Start with purple, then add green, then yellow,

orange, and red last. Go slowly here, we don’t want the different

layers to mix.
