Beefed up

Last week's lab... we were given a small piece of steel which was encased in plastic casing, diameter about 2 one dollar coins. Task: to grind the steel manually against grated paper to give it a nice finish. Method: grab the circular plastic casing with ur fingers, and rub it up and down on the grated paper.

But ALAS!



























Effect of eating too much beef in USA. LOL.
