GARDEN IN A GLOVE<br />

• 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 />
