Handleiding

A small, quiet, cool, and ideally lockable

basement room is much more suitable, and for

your workplace you can use a sturdy table with

a tough, heat-resistant surface that should

always be kept covered with newspaper. Don’t

forget to clean up after your experiments and to

wipe the work surface clean.

Opening the packets

Use a pair of scissors to cut open the packets at

one corner. Never use your teeth. Make sure not

to cut the printed area so it becomes

unreadable.

If the crystal salt has formed clumps, it does

not mean there is anything wrong with the

quality of the contents. Rather, it just means

that some moisture (from the air, for

example) has gotten in. This will not

affect its function. The age of your

crystal salt will likewise make no

difference.

After use, re-close plaster and dye

powder packets with a clip or a

piece of tape.

Cleaning and disposing of waste

Cleanliness is especially important in

chemistry. So always clean up any used

containers and your workplace immediately

after finishing the experiments. Then wash the

containers with clean water and dry them with

a paper towel, which you should then throw

into the trash. Since you will only be working

with small amounts of a harmless chemical,

you can simply wash any liquid waste down

the sink with plenty of water. Solid waste can

go into the household garbage. When disposing

of dyed liquids, be careful to pour them right

into the drain so you don’t stain the sink.

Storing the crystals

Once you have finished them and they have

dried, always store any smaller crystals in the

lockable jewelry box.

Larger specimens can be kept in a lockable

cupboard or on a high shelf, out of the reach of

small children.

TIP !

When you close the box, make sure that the lid

is positioned correctly. To open it, insert a

small screwdriver into the slot on the side and

turn carefully.
