-Very gently, so to not disturb the water, remove the straw...
- Light the bunsen burner and slid in under the tripod so that you are heating the outside of the beaker where the crystal is... then watch.

as the beaker heated the potassium permanganate started to spread more after a couple of seconds the collar purple filled the beaker...

the hot water rises because of it less dense and because the hot water is less dense it allows the potassium permanganate could rise and spread around the beaker...
