Shows that hot water rises, simply and clearly.
Continue with self-circulating heating systems and thermology.
Fill the pipe with water, add a little colouring (e.g. potassium permanganate) and then heat one of the vertical pipes. When the water heats up, it will expand, its density will drop and the water will rise. The water starts to circulate.
Material: Glass.
Dimensions: 17x23 cm.
NB! The pipe in the picture has a stand as extra equipment. Ordered separately.
