Some DIY projects are awesome just for the sake of being awesome. This mini cannon probably has no real, practical purpose, but it is one of the most finely crafted pieces of DIY technology we’ve seen in a long time. And it makes for some exceptionally entertaining videos of everyday items being assaulted, exploded and attacked by tiny steel balls.

The videos of the cannon in action are almost too amazing to be believed. But they’re 100% authentic, and they show how frighteningly powerful firearms are – even very tiny ones.

This second video shows the cannon after its creator added a gunsight and improved the bore, making the cannon more accurate and eliminating deviations. With a minuscule amount of gunpowder and some itty-bitty steel balls, this amazing armament destroys things in a decidedly delightful manner.
