2. Stopper (plug) - Wikipedia

   en.wikipedia.org/wiki/Stopper_(plug)

   For instance, if one were to boil water in a test tube and wanted to collect the water vapor, one could seal the test tube with a stopper with holes in it. With tubing inserted into the hole(s), when the tube is heated, water vapor will rise through the hole, make its way through the tubing, and into the collection chamber of choice.

3. Teapot effect - Wikipedia

   en.wikipedia.org/wiki/Teapot_effect

   The teapot effect, also known as dribbling, is a fluid dynamics phenomenon that occurs when a liquid being poured from a container runs down the spout or the body of the vessel instead of flowing out in an arc. [1] Markus Reiner coined the term "teapot effect" in 1956 to describe the tendency of liquid to dribble down the side of a vessel while ...

   Ordinary ice shows NTE in its hexagonal and cubic phases at very low temperatures (below –200 °C). [9] In its liquid form, pure water also displays negative thermal expansivity below 3.984 °C. ALLVAR Alloy 30, a titanium-based alloy, shows NTE over a wide temperature range, with a -30 ppm/°C instantaneous coefficient of thermal expansion ...
