Water Drops Dance in Burning Hot Pot

-

GUIDE: IT WILL TAKE 10 MINUTES TO MAKE THE EXPERIMENT. Activate the hotplate at its highest temperatur­e.

Place a pot or a frying pan – remember no Teflon – on the plate and wait a few minutes, until it is burning hot. If you have an old-fashioned stove with a solid top, there is no need for a pot or a frying pan.

Mix colour into the water and pour it into a squirt bottle.

The colour makes it easier to see the drops, and the bottle makes it easier to control the quantity of water.

You can check the temperatur­e by pouring a little water into the pot.

If the temperatur­e is not sufficient­ly high, the water drops will spread out and quickly evaporate.

When the pot has the right temperatur­e,

the water drops will remain intact, dancing about the bottom of the pot for up to 30 seconds without evaporatin­g.
