What do you do when you're stranded on a desert island and you've gone through the last of your bottled water? You save yourself and the planet by recycling those bottles into a DIY kayak and outrigger.
Bear Grylls eat your heart out. This Instructable gives you step by step instructions to building a recycled-materials kayak. It's probably the most eco-friendly way of keeping yourself from devolving into a raving bearded maniac if you find yourself marooned on an uncharted island sometime in the near future.
This particular kayak was built for a recyclable boat race, but if you're planning on a Man Vs. Wild adventure of your own anytime soon, this Instructable is a must-read. [Instructables]
