A balloon once scored for Sunderland against LIverpool. You'll use a smaller balloon for this activity - letting nature blow it up for you.
What difference does it make?
Have some fun and learn a bit about how plants turn into energy and gas.
What do you need?
- Small empty bottle - preferably glass
- Rubber band
- Some lettuce leaves or even kitchen scraps (plants only)
Step by step
Get a balloon. Find a glass bottle and clean it with water. And ask the chef of the house for some lettuce leaves.
Chop up the salad into small bits with scissors and push all the bits into the bottle. Fill the bottle with water up to its neck.
With a marker-pen draw your club badge, a face or a football on the balloon. Then fix the balloon over the mouth of the bottle. Tie it with a piece of string. Now wait for the balloon to blow itself up!
It is. Although the quantity of gas is tiny, it is sensible to keep the bottle away from any flame.
You can definitely try different waste foods in different bottles. See which blows up the balloon slower or faster. The fastest we know are bits of lettuce.
Take the balloon off the bottle. Empty the contents of the bottle into your garden waste or compost bin.
