This handy gentleman has built an (arguably ill-conceived, but nevertheless impressive) rifle-cum-slingshot that fires machetes, should you find yourself with the need to fire machetes.

The handy gentleman in question is YouTuber Jörg Sprave, slingshot enthusiast par excellence. He blogs about it here. [via Boing Boing]

A Clock That Eats Flies

A Clock That Eats Flies
