The Bulletproof See-Through Kayak
Do you ever wish that the ugly green plastic of your kayak was more transparent? We sure do. If there's a shark down there, we do want to know about it, so we can take care of things. Made of an incredibly strong Lexan—the same polycarbonate used in NASA astronaut bubble-helmets—Clear Blue Hawaii's Molokini Kayak is 100 percent clear.
Clear Blue Hawaii touts the Molokini as being capable of withstanding "intense crashing against rocky shorelines, 20-ft drops, hammer blows, and an ejection from a vehicle at 70mph." We really want that tested on YouTube.
