Science Marathon (Scithon)
Subject: Physics
Instant-Freeze Water
Freeze water instantly by sharply knocking a bottle of supercooled liquid water. It may look like magic, but there's some pretty cool science behind it.
Fire Vortex
Analyse the behaviour of fire tornados which occur naturally in forest fires by building your own fire vortex. Be amazed by this physics phenomenon!
Collapsing Metal Can WIP
Exerting a change in pressure in a metal can by creating a vacuum inside, resulting in an implosion caused by the atmospheric pressure.
Compasses: How do they work? WIP
Understand how compasses work - and how they malfunction! A great way to learn about magnetism, magnetic materials and the Earth’s magnetic field.
