  • Anti-Gravity Cone?!

    Anti-Gravity Cone?!

    Einstein thought it impossible: a ball rolling uphill! This new experiment shows, for the first time ever, a ball can actually defy gravity.

    The next video released will explain how the Anti-Gravity Cone actually works; what force overpowers the force of gravity?

  • The Coriolis Effect

    The Coriolis Effect

    The Coriolis effect says that anytime you’re rotating—whether it’s on a playground toy or your home planet—objects moving in straight lines will appear to curve. This bizarre phenomenon affects many things, from the paths of missiles to the formation of hurricanes.

    You may have heard that the Coriolis effect makes water in the bathtub spiral down the drain in a certain way, or that it determines the way that a toilet flushes. That’s actually wrong.

    Although, as you may have noticed while tracking a hurricane on the news, storms in the Northern Hemisphere spin counterclockwise, while those in the Southern Hemisphere spin clockwise. Why do storms spin in different directions depending on their location? And why do they spin in the first place? The answer is the Coriolis effect.
