This video explores the interaction between ferrofluid and a superconductor. The host demonstrates how the superconductor repels the ferrofluid's magnetic field, creating a unique visual effect. The video also features a large-scale experiment where a liter of ferrofluid is poured onto a powerful neodymium magnet, resulting in unexpected and fascinating behavior.

This video demonstrates a device that spins a ball bearing in a circle without any apparent external force. The creator explains that the device is inspired by the "Egg of Columbus" and uses electromagnets to create a spinning force. The video also explores the physics behind the phenomenon, including the role of friction in lifting the spinning object.

The video explores the behavior of perfectly fitted steel pieces in a vacuum. The host investigates how air pressure affects the movement of these pieces, demonstrating the surprising phenomenon of air viscosity remaining relatively constant even at extremely low pressures. The video concludes with an explanation of why this occurs, highlighting the relationship between viscosity and the ability of gas molecules to slip past each other.
