A list of 1 minute(ish) films with some amazing toys/time wasters.
I love the ball in the air - looks like magic and just needs a ping pong ball and a straw!
And his Bernoulli effect toy is great and educational!
I am a bit in awe and need to find some kids! I have never liked them much but this is one of those things that might make them bearable!
