Because some people have all the fun, this is a video of Youtuber The Backyard Scientist destroying things with a 400MPH rocket powered slicing warhead he constructed from six kitchen knives. Is this actually science? Yes, and the best kind: the DANGEROUS kind. *twirling tips of evil villain mustache* Yessss, yessss — I’m getting excited about my own experiments just thinking about it.
Keep going for the video, the really good stuff starts around 8:55.
