You
know you want this for Christmas, Chad. You do.
I spotted this on Channel 5's
The Gadget Show tonight, and is as cool as it looks. It can go 30mph on the surface, 20mph underneath, and looked about as agile as a torpedo-driven eel on TV.
This is a prototype, and I like it loads. You can dip underwater and then shoot out up into the air! Better than the one made by Proffesor Calculus, anyday.
