When they're not organising workshops in the LYSC, Jemma and Joe test their scientific skills against each other. See who can make the best rocket, then make one for yourself.
Do you have the engineering skills to take on Joe? Can you build a better space craft than Jemma? You might not have a bike pump launcher at home, but that doesn’t mean you can’t get in on the action. Try this easy method, then go larger with the explosive rocket activity video below, from our ExpeRimental series.
Thick drinking straws
Try making a few different rockets to investigate which designs work best. Does a larger rocket go further? Does it make a difference if you don’t include a cone on the top?
Once you've created the perfect paper rocket, and seen how far you can launch it with your breath, try propelling a drinks bottle into the air with some fizzy tablets. Get all the instructions and download the information sheet here.
