The Pythagorean Cup
According to legend, Pythagoras invented a cup to prevent his students from drinking too greedily. If they overfilled the cup, it would immediately drain out all the fluid. The trick Keep reading
Crash Course Hydrostatics
Crash Course Physics has just put out an episode on fluids at rest (a.k.a. hydrostatics). For those who are unfamiliar, Crash Course is an educational YouTube channel that offers fun, Keep reading
Perpetual Motion?
In the 17th century, scientist Robert Boyle proposed a perpetual motion machine consisting of a self-filling flask. The concept was that capillary action, which creates the meniscus of liquid seen Keep reading
Liquid Settling
Despite the strange shapes of the arms on this container, the fluid inside will always settle to a common height. This is because each interconnected section is open to the Keep reading
