Doodle Science - April 2014

Circulated to schools, organisations and individuals - covering primary science and related bits and bobs.


It is a picture of me and my new toy, The OneTesla singing coil. I built this from the kit and it works, utterly amazing, I know I am bound to say that but it is. I am deeply indebted to a certain A. Walker for snapping this at the Southampton University Family day and posting it on my Ian B Dunne says Do Science page on Facebook.

Something to try. Strange Attractor

Charge a balloon up on your hair or the cat or whatever comes to hand, actually don't use a cat they do not like it. Place an empty drinks can on a table so it can role and when you get the can near it it will move toward the can. Quite odd. See that else you can do with the balloon, how long can you get one to stick to the wall. This will vary with humidity as the higher it is the quicker the charge leaks away. Health and safety Don't play with electricity out of the mains
