Students have to design a water-powered contraption that automatically bursts a balloon after a small time delay. They use retort stands, clamps, string, cups, pins, icy-pole sticks, and plasticine.
It’s a fantastic STEM activity which is based on the “Drip Rifle”, which was set up by the Australian and New Zealand Army Corps soldiers in the trenches of Gallipoli in World War I.
The drip rifle hurt no-one, but it saved thousands of lives!
My students love it.

My students often tell me that this is the best activity that they have ever done in school.
Teachers, if you're looking for a hands-on practical activity that will bring out your students' technical creativity in a big way, but which is easy to run in a Science room, you have to check it out!!
