When he's not documenting mods and hacks he's doing his best to make sure a generation of college students graduate knowing they should put their pants on one leg at a time and go on to greatness, just like Bruce Dickinson. You can follow him on if you'd like.

    One of my favorite demonstrations in Jr High was making a penny ‘float’. Fill a test tube with an inch or so of water, Then put a half inch or so of mercury into the test tube. The mercury will sink to the bottom of the test tube. Now put a penny into the test tube, the penny will of coarse sink through the water, but ‘float’ on top of the mercury.
