About two weeks ago we had the incredible fast 150mph rocket knife, now TheBackyardScientist replayed with the highspeed knife, except he added “some” temperature to it. This is silly, dangerous and absolutely awesome!

“You knew it was coming! Back at it agin with the Rocket Knife, but this time im going full sellout 😉 1000 degree, 150mph knife vs Coke, Silly-String, Bread, Wood, Bricks, and Lighters!”
