• disposable glove<br />

• permanent marker<br />

• cotton balls<br />

• water<br />

• 5 different kinds of<br />

seeds<br />

• popsicle stick<br />

• pipe cleaner<br />

What to do<br />

• Use a permanent marker to write the names of the 5 seeds<br />

on the fingers (one type per finger).<br />

• Place a cotton ball in water and gently wring it out.<br />

• Place 2–3 seeds of the same type in one of the wet cotton<br />

balls.<br />

• Put the cotton ball in the finger of the glove that is labeled<br />

with that seed name. You may need to use a popsicle stick<br />

to push the cotton ball all the way to the tips of the glove<br />

fingers.<br />

• Blow a little air into the plastic glove and close the top of<br />

GROSS GOO (PRE-EVENT)<br />

3<br />

Supplies<br />

• 2–4 clean, empty 2-liter<br />

soda bottles with a lid<br />

• Borax<br />

• glue<br />

• water<br />

• 1-cup measuring cup<br />

**Be prepared to make<br />

more of these mixtures<br />

throughout the night,<br />

depending on attendance.**<br />

Borax and Water Solution<br />

In a clean, empty 2-liter soda bottle combine 1 cup of<br />

Borax laundry detergent with warm water. For best results,<br />

combine small amounts of Borax and water at a time. Fill<br />

the bottle with water. Put the cap on the bottle and shake<br />

to dissolve the Borax. Periodically shake this solution<br />

throughout the event. Pour some of this solution into<br />

a cup (about ¾ full) and save the rest to top off the cup<br />

throughout the event.<br />

Glue and Water Solution<br />

In a clean 2-liter soda bottle combine equal parts white<br />

glue and water. It works best to first pour glue into the<br />

bottle until it reaches the bottom edge of where the label<br />

would be. Add water until it is equal to or just slightly<br />

above the top of the label. Put the cap on the bottle and<br />

gently shake the bottle. If you are expecting a large crowd<br />

you may want to go ahead and mix two batches. Pour some<br />

of this solution into a cup (about ¾ full) and save the rest in<br />

to top off the cup throughout the event.<br />
