By hiding some important details, they would get more clicks on the video. I expect identical glass pistons, that press on the scale... -
jbriggs444 replied to the thread B 'splain this hydrostatic paradox in tiny words.I assume that the mechanism includes some sort of identical pistons inside the vertical glass walled tubing. The scale pans are then...
