A Heat Gun
A Heat Gun
A small amount of water is placed inside an airtight copper tube, with the end sealed by a rubber stopper. The tube is heated using a blowtorch, causing the water inside to boil. As the water changes from a liquid to a gas the pressure inside the tube increases. Eventually the pressure blows ...
Plasma turbulence
Plasma turbulence
This computer simulation shows a cross-section of the plasma inside a tokamak reactor. In this simulation, only the large-scale turbulence effects are modeled — which is adequate for some cases

DC Motor
DC Motor
A DC current is sent around a wire loop that is free to rotate. The current causes the loop to feel a torque in the presence of a magnetic field. Switching the current when the loop flips over allows it to continue accelerating, demonstrating the principle of a DC motor and the Lorentz force ...
