Video: If the internet is remembered for anything, it will be as humanity's most comprehensive archive of things you probably shouldn't try at home. Like making your own high-speed spinning toy that can reach speeds of over 100,000 RPMs, and then attaching razor blades to your creation to see what it can destroy.
The results are as wonderfully destructive as you'd hope. Hot dogs, crayons, cans of whipped cream — they all get sliced and slashed by the spinning menace. But the risk of one of those blades coming loose and flying off is just one of hundreds of reasons why you shouldn't try something like this yourself. Leave it to the professionals on YouTube willing to risk life and limb for a few more views.
