Frans, that sounds like an invite, and i would love to see the redwoods, let alone climb them! Although at this moment in my life, that graph would be especially boring, because i can't possibly swing that for quite awhile :cry: You are right about the chart, but they are all very similar in...

A buddy, while in high school and obviously heavily intoxicated, shot a hole clean through the garage roof while messing with one. They are actually quite dangerous. And you can only buy semi auto ones at every store. Our science project, looking back, probably was super illegal, because you...

As far as legality goes, building a cannon that sends spuds into low orbit is illegal as hell, but iirc i even did one for a physics project. We also built an adjustable rate of fire trigger mechanism, to make a paintball gun fully automatic. We had to make it adjustable because it cycled so...
