Anyone who spends even a little bit of time on Imgur knows that Adam Savage is not only an account holder, but an active member of the community. This past holiday season, Savage got more involved than usual and entered the site’s Secret Santa program. With the work ethic you’d expect from one half of the Mythbusters, Savage put his shop to use and modded a store-bought NERF gun, turning it into something closer to what a military-sponsored foam dart gun would look like. You can see the whole process in Savage’s Tested, a YouTube series that plays like a more curated, more personal continuation of Mythbusters. We get to see Savage’s method step by step, so you’d be able to replicate it if you have the gumption (and materials, money, time, and patience). If you do, be ready for some seriously raised stakes at your next NERF battle.

Shift-Infeed

If you’re anything like us, you perpetually suffer from inbox overload. If we’re only reading one email a day, it’s going to be SHIFT. SHIFT is for guys who are not afraid of change. Guys that understand small things can make a difference. Guys that are willing to question what they think. It’s for guys just like you. Two times a week, SHIFT delivers content around the mind, body and movement–along with some appropriate eye candy–direct to your inbox. Their goal is to remind all of us that every man should give a SHIFT.
