I know that sounds ridiculous, but I’m pretty sure that you’d have Michelle Obama arms after just a day or two. Why? Because everything you need is operated by hand crank!
GearJunkie describes it like this:
The SteriPEN Sidewinder has a crank arm to power its water-purifying UV-light mechanism. The result is a protozoa-zapping contraption that purifies suspect water and can go completely off the grid.
Step 1: Fill the unit’s one-liter bottle and attach the Sidewinder.
Step 2: Flip the bottle and Sidewinder upside down and unfold the handle.
Step 3: Crank until green LED indicates successful purification.
Step 4: Drink up!
The Sidewinder isn’t available quite yet, but come September it should retail for $99.95.
So what do you think? Could cranks be the new secret to our First Lady’s fighting figure?
