Ah. Reminds me of our Advanced Chemistry class one day.
Apparently, our teacher was absent (as usual), so we decided to pull off table hockey with some five-peso coins. The prize was...a pile of paper aircraft. While the table was rigged (the odds never were in my favor), so I lost. Eventually, we ended up just playing with the paper aircraft.
An application of physics in a class meant to be about applications of an application of physics.
