Here is a teapot that has two separate compartments, allowing you to pour separate drinks depending on where you place your fingers. Let’s say you would like to poison someone but don’t want to make them suspicious. This teapot lets you do that easily. Just make sure you remember which compartment has poisoned tea or coffee.
In reality, you can use this teapot to serve coffee and milk at the same time. The teapot is made of green glazed porcelain. More information is available here.
