Hello colleagues

today, in the channel "magic and curiosities"

let's make a very curious home experiment

Who has never been amazed

with the "lava lamps"?

watching the lava go up and down

today we are going to achieve a similar effect

with some simple moth balls

children should do this experiment

supervised by an adult

you must put the moth balls

far from the reach of young children

because they can be confused with candies

and the moth balls are an insecticide

let's see the experiment

to do this home experiment

we need moth balls

of those that are put inside the cupboards

to kill the moths

a bottle with water

sodium bicarbonate

and vinegar

we put a little bicarbonate

inside the bottle with water

next we put moth balls

we shake to dissolve part of the baking

we take vinegar very carefully

slowly, so that the water does not overflow

we'll wait a little

and the moth balls will start their dance

which can last more than an hour

the dance of the moth balls
