Simple Science Project - Rocket blast off

by Nicola
(Australia)

Here is a simple science project for you to do.

My brother and I (with mum's help of course) combined water and vinegar in a plastic bottle. Mum rolled up some bi-carb in a paper towel and she twisted the ends like a lolly. We decorated a cork that fit the bottle with red streamers like a rocket. We sat about 3 metres away while mummy put the bi-carb lolly in and put the cork rocket very quickly in. We counted down but nothing happened!!!

So mummy had to shake it to help blast it. A bit later the cork blasted off into the air. It went really high! Why you ask? Because bi-carb mixed with vinegar makes a gas that rises and pushes the cork out with the force of air.

Congratulations to Nicola, Jasmin and Ethan for winning August's Homeschool Freebie for listing their Simple Science Experiment.
