Jason Fitzpatrick is a warranty-voiding DIYer who spends his days cracking opening cases and wrestling with code so you don't have to. If it can be modded, optimized, repurposed, or torn apart for fun he's interested (and probably already at the workbench taking it apart). 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.
