Last week, we inaugurated a new challenge for you here on PopSci.com that lets you show off your deep tool knowledge and walk away with not only our abiding respect, but a less obscure tool of your own.
Here's how it works: We post a picture of a strange object from my shop, maybe a clue or two, and you guess what it is in the comments section below. The first and most precise among you to guess correctly will win the prize. This week, it’s a 30-foot Stanley FatMax tape measure. Pretty sweet.
This week, the obscure object is something I was given by a company that had gone out of business. What kind of work did that company do, and for what was this machine used?
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
