Kayak submarine

That was pretty cool.  Looks homemade, but it appeared to work pretty well.

It was homemade and it is pretty cool. I'd give it a try with minimal arm twisting. I saw it in a blog and there was this amusing header for it:

And to think your mother wouldn't let you have a BB gun because you'd shoot your eye out.

Of course, a BB gun is no where near as dangerous as a kayak. This fellow no doubt built a submarine out of a kayak to make it safer. If you're going to end up upside-down with your legs in a knot in a sort of socket, you might as well be watertight.

If someone buys you a kayak, keep an eye on that person. They mean you no good. Have any food they offer you tested. Check under your car when you leave their house. A person that purchases you a kayak is not to be trusted.
