um...
it makes...
FIRE!!!
(the piece of potassium zips around the surface of the water and burns as the two react)

It depends on the oxidation state of Potassium. If it is in the form of potassium nitrate, then it will just dissolve in water.
If it is in the form of metal, ie elemental metal with oxidation state of zero, then putting it in water can be dangerous and explosive because the reaction is very exothermic, generating so much heat and liberating lots of hydrogen gas. The heat is enough to cause fire when oxygen in the air reacts with the fuel hydrogen generated. And depending on the amount of
potassium, you can burn yourself and everything else. Moreover, the solution formed is very basic from KOH and this will corrode and burn your skin. Bad all the way through.
Do not trifle with this unless you have good safety equipment like a hood, etc.

Forms potassium hydroxide, liberates hydrogen which ignites from the heat for some nice pops.
Get an "A".

is potassium in its ionic form? if so it will react with the water to form potassium hydroxide

The hydrogen will ignite.
