Handleiding

Preparing the

plastic insert

The kit’s pink insert consists

of various basins and

containers along with a

plaster mold. Separate the

individual parts from one another

and smooth their edges with a little

sandpaper. Have an adult help you with this.

To heat the solutions…

…you should use clean, empty jelly jars. But

never, under any circumstances, set the jars

directly on a burner or gas flame. This would

make glass containers crack and break, and

plastic containers would melt.

Instead, get an old cooking pot, around 20 cm in

diameter, and fill it with a few centimeters of tap

water. The water level should be slightly lower

than the level of liquid in the crystal-growing

container. Heat the water on the burner to just

under the boiling point.

Carefully carry the pot to your work area

(ideally, have an adult help you), and set it on a

trivet or hot pad. Now place your growing jar in

the pot and stir its contents with a wooden

spatula. The water will warm the jar contents,

and the crystal salt will soon dissolve and

completely disappear.

If the crystal salt does not dissolve well, take the

growing container out of the pot with a

potholder and heat the water on the burner

again, and then try to dissolve the salt one more

time. Careful! Don’t burn yourself with the hot

water or on the pot, and don’t forget to turn the

stove off again. Wear your safety glasses!

Always have an adult help you when heating

water or solutions! Do not work alone!

Also, be very careful not to burn yourself or

scald yourself with hot water, and don’t spill

any crystal salt solutions! Don’t inhale the

steam that comes off the crystal salt solutions

when you heat them!

TIP !

This is how you can label your jelly jars: Write the name of the

crystal salt solution with a pencil or ball-point pen on a

narrow strip of paper, and secure the paper to the jar by

placing a piece of tape over it. If you use self-adhesive

labels, cover the label with a piece of tape as well. Get two

containers with lids ready to hold your supply of alum and

ammonium biphosphate solution, labeling each container with

the chemical’s name.
