LOL! My Son's HS Physics competition project. Iowa State University
Physics department puts on a competition among HSs to build a roller
coaster device that demonstrates 10 laws of physics while keeping a
steel ball in motion for 2min and do something at the end; that year it
was close a circuit to light a bulb. His group couldn't get this one to
work on cue for the judges but it was a crowd favorite getting alot of
attention from the100 or so in attendance. They won the competition
the year before with a less elaborate but still impressive one.
