Pineapple and fingerprints
Here’s an experiment you probably shouldn’t repeat at home. Not because it’s particularly dangerous, mind — more that it’s going to really really hurt. Lots.
Tom Scott tests out the often-repeated notion that you can remove your fingerprints by soaking your hands in pineapple. His film is brilliant, even if the experiment… umm… isn’t the most sensible I’ve ever seen.
Credit for dedication, though.
