Air Bubbles
Like dolphins: forming rings that rise. By pumping air into the glass tube filled with water, air bubbles rise. They ascend vertically. Often in a straight…
Air cushion
Inventive talent is called for here! Use scissors and tape to build objects out of paper that float on the wide air cushion. While testing and optimising, you…
Cartesian Diver
Sinks / Doesn’t Sink Sometimes called a “Cartesian diver,” this hollow body is partially filled with water and air. Depending on the pressure in the liquid,…
Fog wind tunnel
Streamlines become clearly visible. This is how flowing air behaves: when it encounters a shape, it hugs its surface and gets deflected. The wind tunnel…
Slow Bubbles
«Slow Bubbles» Beautiful, how the bubbles rise slowly. In the thicker silicone oil, they have significant buoyancy but also more friction than in water. This…
Soap Bubble Basin
Loooong bubbles For kids big and small: form soap bubbles several meters long. Sometimes, a bubble stretches into a tube large enough for a child to fit…
Condiment Diver
To paraphrase French philosopher René Descartes: "I sink, therefore I am." Changes in fluid pressure affect the buoyancy of a Cartesian diver made from a…
