Remember when The Backyard Scientist Kevin Kohler sliced through stuff with his rocket knife? Good times. Cool as that was, he knew he could do better, so he has now launched a 1,000° red hot rocket knife at a bunch of stuff just to see what would happen.
He slices a bottle of Coke, cans of Silly String, bread, and a row of lighters, packed with explosive butane. Needless to say, all of them are effortlessly sliced in half. At 1000º and 150 mph, there’s not much that can stop this knife. It even slices wood cleanly.
This is definitely a fun and dangerous rig. Don’t try this one at home, kids.
