Firefly Light

Not sure how many folks get stuck out there in the wilderness without a light, but here’s a really cool device that turns your water bottle into a lantern. Called The Firefly, it seems pretty handy. You merely use your regular big mouth Nalgene bottle and screw the Firefly on top. When you turn it on, zoing! you get a nice lovely light.

Of course, if you want to get really tricky, you can use all sorts of different colors of Gatorade and make neato colors. This might serve you well if you need to line up a while bunch of these to make an airstrip or something. Come on, professor, you’ve watched Gilligan’s Island. Just think how useful these would be!
