Filling or Draining a Water Bottle with Two Holes
Cross, Rod
Physics Education, v51 n4 Article 045014 Jul 2016
Three simple experiments are described using a small water bottle with two holes in the side of the bottle. The main challenge is to predict and then explain the observations, but the arrangements can also be used for quantitative measurements concerning hydrostatic pressure, Bernoulli's equation, surface tension and bubble formation.
