Handleiding

TIP!

You will have to work very carefully! If

dirt gets into the crystal salt solution

or if the cup is shaken while cooling,

the crystals will form too quickly.

CAUTION!

Have a grownup help you! Be careful

not to burn yourself on the hot pot,

and don’t forget to turn the burner off

afterwards!

1. Disappearing

crystal salt

You will need:

1 packet crystal salt (sodium acetate),

measuring cup, petri dish, wooden

spatula,

clean jelly jar with lid, distilled water,

pot, trivet, and pot-holder, scissors,

paper label, pencil and tape

Here’s how:

Fill an old pot to a depth of 3

cm with water and set it on the

burner to heat. Get a trivet and

a pot-holder ready at your work

station.

Cut off one corner of the crystal

salt packet with the scissors and

pour the contents into the empty

jelly jar. But be sure to save a

few sodium acetate crystals in

the closed petri dish for the next

experiment.

Use the measuring cup to

measure 4 mL of water and add it

to the jelly jar.
