Altoid tin alterations are pretty popular among the hacking community, but this one takes it down in size. Using the Altoids Slim tins, Instructables user Joshua Zimmerman put together these bite-sized LED flashlights for under $5. With just a tiny bit of drilling and soldering, you could easily assemble a handful of these in an hour or two.

The Hungarian Forint is used in very large quantities ($1 USD = 218 Ft) so the government recycles a few tons of it every year. After shredding it and bundling it into bricks, the currency is shipped to charitable organizations to help with their heating cost.

I have absolutely no idea what process engineering is. But from now on whenever hear that word I'm going to think of this. And so should you.

Water-Powered Jet Pack

Zapata Racing just released the Flyboard, a water-powered jet pack available to the public. The Flyboard gets it propulsion from a jet ski idling nearby; its hose forces water to shoot out of the user's feet. Not as cool as a the real deal the public is waiting on, but I guess this is a happy medium for now.
