There’s a whole corner of YouTube dedicated to destroying random objects in oddly satisfying ways, and the channel Mr. Gear may have hit the sweet spot with this experiment. This video of a red-hot knife slicing through soap, post-it notes, a plastic Coke bottle, and more has racked up over 41 million views in just four days.

The experiment begins with someone heating a chef’s knife up to 1000ºF with three blowtorches. From there it’s ready to slice through everyday items with sizzling ease. It’s fascinating to see how the different materials react to the heat, from the instant grilled cheese to the ping pong ball bursting into flames. After watching the video above, heed Mr. Gear’s advice and refrain from performing any tests of your own at home.
