  3. Cracking idea! What's the fit like between ball and tube? In a very similar vein an old bucket, some polythene and elastic can make a very effective Air Vortex Cannon, with the benefit that the projectile itself is made of air.

  4. Thanks Jim. In the model shown in the video the fit is fairly loose — maybe a couple of mm spare. In a subsequent version I have a contact fit. Performance is a bit better with the snug fit but it varies quite a lot with the nuances of your stomp. Both seem to cause large amounts of fun.
