Fluids

Wind tube

This is a very simple and yet very effective exhibit. Basically just a fan blowing upwards past a gap into a clear tube. Visitors can make different flying machines out of paper, polythene, paperclips or whatever, put them in and see what happens. It is an exhibit which can captivate a one year old or a PhD engineer.

We have made a variety of these, and the top of the tube can be up to 3m high
