Science fair

Magnetic levitation is a phenomenon that combines physics and wonder, capturing the imagination of anyone who sees it in action. From science enthusiasts to educators, showcasing magnetic levitation is a perfect way to explore advanced scientific principles in a visually...

A levitation project stands out at a science fair because nothing else on the table is doing it. The catch is that the best version needs liquid nitrogen, and the version that needs none is a different project with different...

This project levitates a small train on permanent magnets alone — no liquid nitrogen, no cryogenic handling, no special safety kit. That makes it one of the few levitation projects you can build and demonstrate in an ordinary classroom. If...

A superconductor cooled in liquid nitrogen will hang in mid-air above a magnetic track and glide along it with almost no friction — a real hoverboard, at desk scale. It also makes an unusually strong science fair project, because unlike...
