We know what tornadoes are.
Today we saw one in action.
If you have two bottles of the same size connected with a connector you can swirl the top bottle and get a tornado moving. (A vortex)
It really is spectacular!
A big Thank You to Atlantic Technological university (ATU) for helping us to get involved in their excellent Rainbow Lab.
