This is a simulation of how the reaction of iodine with α-pinene was used as a form of antisepsis.
Spikes in aqueous ferrofluid are formed in response to a magnet.
The reaction of magnesium with carbon dioxide (dry ice) is demonstrated. Despite the absence of air, the magnesium continues to glow.
A piece of copper metal is heated in a flame and oxidized to black copper oxide by air. The oxidized copper is reduced when placed in a hydrogen atmosphere. When removed from the hydrogen atmosphere, the metal is again oxidized.
