The Assassin’s Teapot belongs to a family of similar trick vessels (Think A Drink, Any Drink Called For, Inexhaustible Bottle, The Magic Kettle). They all rely on surface tension and atmospheric pressure to work.The assassin’s teapot was made to poison your enemies. It does this using two hidden chambers.

One housing your standard drinkable drink and another holding your enemies’ just dessertsThe trick is simple. Two separate cavities exist within the teapot, exiting via their own paths in the same spout. Each cavity also has an air hole in the top. If the hole for a given cavity is blocked by the pourer’s thumb, the liquid will not flow.
Each cavity can be filled with its own liquid. For example, one can be filled with tea, the other with poisoned tea.The workings are simple, if air cannot flow into the cavity of the teapot to replace liquid flowing out, air pressure will stop the liquid flowing at all.
