With respect to "drinking normally" when the cup is filled below the siphoning point: if you drink by tipping the cup towards the drain pipe, wouldn't that engage the siphon?
- DiThi 10y agoThe drain pipe is as close to the center as possible. When you tilt a cylinder half full of water, the point at the center remains at the same height. Considering the cups are slightly wider at the top than the bottom, it can hold more liquid when tilted, so the height at the center would be a bit lower.
