Andreas sets out to prove the theory of heat transfer by taking a ride through a searing hot fire.

It is harder to move in water than it is in air. To show the difference in resistance, physicist Andreas Wahl will stand in front of a weapon immersed in water and fire it - at himself.

To prove that the law of energy conservation is absolute, physicist Andreas Wahl pulls a one-tonne wrecking ball up to his face, drops it and stands still while it swings back at him.

In the human body, the blood vessels conduct electricity the best, and straight to the heart. Physicist Andreas Wahl proves electricity goes the way of least resistance by dressing with metal and being struck by lightning.

How much suction is needed to hold a man up? Using only two vacuum cleaners and two homemade suction cups, physicist Andreas Wahl climbs up a 40-meter-high glass wall.

Physicist Andreas Wahl investigates frictional forces by interweaving two telephone directories, attaching one end to a bridge and the other to an elastic band, and jumping off the bridge, 70 meters above ground.

Have you ever seen a balloon seller and wondered how many balloons could lift him up? To prove buoyancy, physicist Andreas Wahl gathers a cluster of giant helium balloons and takes flight.
