by Danny Briant Simple cheap helium gun - the helium isn't as cheap! Inspired by KJBubbleguy aka Keith Michael Johnson. See his excellent videos for inspiration on how to play with this toy. What you need: * One balloon * One piece of plastic pipe/flexible tubing * One nozzle from a carton of wine The tricky bit is getting the right size tube for your particular nozzle. Loo in your local hardware shop. Daniel Dyboski-Bryant July 20, 2014
