Exploding Baggies

Equipment Needed

Zip lock bag

Gaffa tape

Sharp pencils

Water

Food Colouring (optional)

Mix food colouring with water. 

Pour water into bag so it's about 3/4 full

Zip up bag and tape over the zip

The water doesn't leak out because the molecules in the bag move and create a seal with the pencil
