IMPORTANT: You will need one sober adult with a sense of scientific wonder......
What you need to get started is: A small packet (75g) of yeast, a small plastic bottle, a balloon, granulated sugar, warm water, a jug and a pair of scissors.
1. Get a 500ml bottle of water and fill it up an inch high with hot water
2. Pour 75g of yeast into your bottle
3. Add a tablespoon of granulated sugar
4. Blow up a balloon to stretch it out a bit and let it deflate
5. Now cover the top of your bottle with your deflated balloon
6. Give the bottle a shake
7. Your balloon should now begin to slowly expand over time as the co2 tries to escape
Live Experiments: Our resident daredevil science fiends will give the YouTube audience their big science treat each week with an experiment where you can find out how to make food dance, power a light bulb with household objects and create mega smoke rings!
