There are so many reasons to try this at home tonight: you get to see the metal blade burn that glorious fiery orange red, you get to hear inanimate objects make weird whining sounds as they get sliced open, you get to imagine what spontaneous self-combustion would be like, and in some cases you might even spot what looks like souls escaping from a bar of soap (that’s probably my favourite thing that gets cut).
The only downside is that you’ll probably burn yourself silly. But still, there are so many fun things that happen with a 1,000 degree knife slicing things that it might be worth it to see what happens.
