The Water Climb weighing scale would likely turn into an impromptu cold shower
I never weigh myself, as I dislike bad news. But if I did, I’d take a look at this concept scale from Jaeyoon Park, Dajeong Kim and Jeong Heo. It’s called the Water Climb, and the most complex part it has is Archimedes’ principle of displacement.
The scale consists of a box, a bag and a graduated glass tube. You fill the bag with water, place it in the box and attach the tube to a hole in the bag. Then you jump on and water is displaced up the tube, allowing you to read off your weight.
Or does it? For this scale to measure my weight, I’d have to displace my own weight in water. Lets pretend that I weigh 70 kilos, or around 150 pounds. To weigh me, wouldn’t 150 pounds of water have to shoot up that tube? I imagine what would happen when I stepped on the scale would be a spectacular fountain of water, followed by a very wet room.
Still, I guess it doubles as a weight for supporting a parasol in the summer.
