Something on a lighter note....
This week I helped my dear wife do some science demos for a kids holiday club that our church ran. She found this really cool demo on Steve Spangler science labs: Make your own Vuvuzela sound. You place a nut inside a balloon and can make a sound just like a vuvuzela. Its great!
Another nice one is clicking the soccer ball beneath any youtube video at the moment. A little demonstration of how annoying those things must be.
