Science Sunday: Homemade Confetti Launchers

Post Author: Mark Dixon & Aoife Ryle

Happy New Year! For the first Science Sunday of 2020, we decided to keep in the festive spirit by showing you how to make your own confetti launchers. The supplies are simple: an empty toilet paper tube, a balloon, and confetti. Leave a little bit of space at the end and stretch the balloon over the end of the toilet paper roll. Then, fill the toilet paper roll with confetti. Just like that, you have a confetti launcher! 

So, what’s the science behind how a confetti launcher works? To launch the confetti, we will be converting potential energy into kinetic energy. To store up some of that potential energy, we pull back on the balloon. To launch the confetti, this potential energy needs to be converted to kinetic energy. We do this by releasing the balloon.

On Saturday, January 18 we will be kicking off Technovation Girls Connecticut here at the Connecticut Science Center. Technovation is for girls, ages 10-18 interested in learning about coding and collaborating with other girls in the state. The kick off event is 10AM-1:30PM. Those interested must register by Friday, January 10, 2020. Visit CTScienceCenter.org for more information.
