This video demonstrates a convection experiment for GCSE Physics using potassium permanganate in water with a Bunsen burner.

Convection can be demonstrated when potassium permanganate, also know as potassium manganate (VII), is used as a dye to show the motion of the water when it is gently heated.
​
CAUTION: Safety goggles should be worn as a Bunsen burner is used and potassium permanganate in its solid form is an oxidiser, harmful if swallowed and harmful to aquatic life.
