Ball in cylinder

Ball in a cylinder is a experiment that we did in the science lab.There were lots of cool experiments but this one was denfinitly We did this experiment because this week is national primary science week. This is how you do this experiment.

Plastic jar


1. Place marble inside jar. Hold jar on the side so it is horizontal, cover the opening with your hand and start spinning the marble.

2.Continue to spin the jar while turning it until the marble is on top of the opening.

Why does this this happen?
This happens because when you spin the marble you are creating a force. When you continue to spin the marble the force will still be there.
