Not only ammunition-resistant, it's see-through too...
Straight out of a James Bond movie is this invention from Clear Blue Hawaii.
The transparent kayak means you can see straight through to the water below (great for spotting a school of fish, terrifying if that school has a shark in its midst). Made out of military-grade bulletproof glass, you can take comfort in the fact that if the shark happens to be holding an AK47, you'll (probably) live to see another day. Boasting a carbon Kevlar frame means the kayak is also super-light - perfect for flinging on dingy canals or the high seas alike.
We don't know what we'd use it for, but we really, really want one. Get yours here.
