These Christmas poppers work in a similar way to the ball launcher that we made in session 8. The Christmas popper converts potential energy, that you add to it, into kinetic energy, when you let go.
The first thing that you will need to do is tie a knot in the end of your balloon and then cut off the tip.
You can then stretch the balloon over the end of your toilet roll tube. You may find it is easier to stretch your balloon if you blow your balloon up first and then let the air out
You then need to tape around the edge of the balloon to seal it in place
Your Christmas popper is now ready to test!
Remember not to aim it at anyone!
You might like to collect some different things and see what happens when you shoot them from your Christmas popper. Does the weight of the object change how far it can fly? Does how far you pull back on the balloon make a difference? What is the longest distance you can make something travel?
The video tutorial for this activity is available on the Surrey Libraries Facebook Page or the Surrey Libraries YouTube Channel
