need something stupid to build
 

i've built every stupid thing i can come up with in my beer soaked brain.
anything from 125 mph single seat long travel buggies to full on 4 wheelers to
a lifted turbo'd cushman to a 175cc 4 speed 4 wheel scooter with a stake bed that fit a 24 of beer perfect.(i never did drive it to the beer store to get beer)
i forgot to drain my pressure washer over winter and the pump froze and split.
i now have a 5 hp horizontal shaft engine that has 5 hours on it begging to be put to use.

any ideas?

Get a vertical shaft engine as well and build a hovercraft.
