Playing around on Tom Thomas' globe leads Nolik to learn about the Earth's gravity and why there is day and night

Simka and Nolik try out Tom Thomas as a candy taste tester, but soon Tom Thomas has a tooth ache from eating so much candy.

Friction can be quite strong. Dr. Boyd shows you just how strong it can be with this demonstration.

This material, inspired by gecko skin, has the unique ability to stick to smooth surfaces like fruits, water bottles, and bags without being sticky. Developed in Professor Mark Kokuski's lab at Stanford, it mimics the van der Waals...

The Hilbert Hotel is an imaginary hotel with infinite rooms, each numbered sequentially. Despite all rooms being occupied, the manager can still accommodate new guests by moving current guests around. With an infinite number of guests...

Google Chrome, Mozilla Firefox, Microsoft Edge, and Apple Safari dominate the web browser market share, but there are new emerging alternatives like Arc, Brave, and Ladybird that could shakeup the Internet over the next few years. Topics...

Kites fly because of the aerodynamic forces of lift and drag. The difference in air pressure on the top and bottom of the kite creates lift. The drag is created by the friction of the air flowing around the kite. The lift balances the...

Light is affected by black holes because of the theory of general relativity, which states that any massive object warps the spacetime around it. Since a photon travels by the shortest distance between two points, light appears to bend...
