Watch This 150mph Knife Speed Through Anything in its Path

Don't blink or you'll miss this rocket knife whizzing down a track and slicing through nearly everything in its path.

What happens when you strap rockets to a knife and send it speeding toward random objects?

Backyard Scientist recreated one of his favorite MythBusters videos using a rocket track, a sharp knife, random objects and tons of propulsion. The craziness got recorded at 3,000 fps, plenty to break down each slice frame by frame.

But, in keeping with internet trends, we can't help but wonder what would happen in a video called EXPERIMENT: RED HOT ROCKET KNIFE?
