As I’ve mentioned before, I’ve got a real affection for the sort of obsessive folks who put together Rube Goldberg devices. Recently, a team from the Society of Professional Engineers at Purdue University set the world’s record for Goldberg devices with a machine that inflates and pops a balloon in 300 steps. It is gloriously excessive.
The only downside is that it is so complex that it’s impossible to keep track of what’s going on. Still, it’s dynamic enough to be fun to watch.
