For this experiment you need 3 empty coca cola or any other bottles, 1 straw, 2 pipes and some water. Just follow instruction in this video and you make Heron’s Fountain!
This project shows how potential energy can provide power, using water and gravity, and air and compression.These are fundamental aspects of pneumatics and hydraulics.
And Heron’s fountain also lets you have a bit of fun during the process.This is a really easy build and would be a perfect project for to build with your kids. Maybe you could even sneak in a lesson on fluid dynamics or perpetual motion?
