Science Club – Rockets

This evening at Science club, our theme was rockets. We looked at how rockets have to have a very large upthrust to escape the Earth’s atmosphere. The children made straw rockets, and film canister rockets. They also looked at the chemical reaction between vinegar and bicarbonate of soda to make a plastic bag pop. We then went outside to find out which type of fizzy drink had the biggest reaction with mentos. It was the diet coke! Finally, we fired water rockets by pumping air into the bottles until it couldn’t contain the pressure anymore. Our second one flew so far we think it may have landed in Carys’ garden!
