The potassium creates a small explosion. Afterwards there will be a small green flame.

A2. This is a dangerous experiment, as potassium has a vigorous reaction with water. It will react with the moisture in the air with sufficient vigor to dissociate that water into oxygen and hydrogen which will again react. This sort of experiment must only be performed under an inert gas environment.

Additionally, the potassium sample will have a surface film of kerosene from its storage, and this burning will add to the hazard. The flame is an orange-red.
