Go-Pro cameras mounted on top of Hot Wheels cars gives us the experience we all imagined as kids. Impossible stunts, insane speeds and, now, different worlds. They call this the "Hot Wheels Nightmare," but it is more like a cross between a bad trip down Mario Kart's Rainbow Road and an electronica concert. We are still impressed that a Hot Wheels car can stay stable with a camera attached to its roof, even to the point of jumping through a rind of fire and landing upright on the other side. Just don't watch if you are afraid of paper face cut-outs that resemble clowns.
