And people always act surprised when I say physics was my favorite class…
Could you imagine back in the 60′s doing something like this high?
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.
