Heureka's Wheel of Misfortune, episode 1

Science fact from the video
The temperature of liquid nitrogen is -196 degrees. The cabbage's liquids freeze and a hard blow causes it to shatter in the same way as glass or ceramics. Freezing takes several minutes, even with nitrogen, because the heat is slowly transferred from between the layers of cabbage leaves.

Science fact from the video
Some special types of soap designed to float on water have a large number of tiny air bubbles mixed into the soap. As the air in the bubbles heats up, their volume increases. In addition to this, the liquid water in the soap evaporates and expands. The increase in volume can be seen as the expansion of the bar of soap.

Science tip from the video
The temperature of liquid nitrogen is -196 degrees. Without air, the movement of atoms and molecules decreases as the temperature decreases. A decrease in movement also means a decrease in pressure. The rubber of the balloons is stretchy and resistant to shrinking and swelling.

Science tip from the video
Styrofoam is polystyrene foam with very little solids and lots of air bubbles. The solid dissolves in the acetone, the air bubbles break up and the air is released. Acetone is toxic by inhalation; In Heureka, the experiment was conducted in a laboratory with enhanced ventilation.

Science tip from the video
Potassium carbide reacts with water melting from ice to form highly flammable acetylene gas. The resulting flame melts more ice, releasing more acetylene gas.

Science tip from the video
The aluminum in the can reacts with sodium hydroxide to form sodium alumate and release hydrogen gas. Some cans use a thin plastic film as the inner coating of the can. When the sodium hydroxide has eaten away all the aluminum, all that remains is the thin plastic inner coating of the can.

Heureka moments

Heureka moments are videos in which hilarious, funny and startling scientific tricks are performed. They remind us of the ultimate essence of doing science – playful experimentation and the joy of insight. You can test many of the tricks yourself. Note! The videos are in Finnish.
Heureka's wheel of misfortune

Welcome to Heureka's laboratory, a quiet place of creative destruction. This program series focuses on destroying things in the name of science.
