Handleiding

With this kit, you and your child will be

able to grow animals and castles made of

sodium acetate in a matter of seconds.

The sodium acetate chemical contained

in this kit is non-toxic and is also used as

a food additive (E262a). Nevertheless, the

safety standard for crystal growing sets

stipulates that parents should provide

their children with help and advice. So

please read the following advice carefully:

A. Read and follow these

instructions, the safety rules and the

ﬁrst aid information, and keep them for

reference.

B. The incorrect use of chemicals can

cause injury and damage to health. Only

carry out those experiments which are

listed in the instructions.

C. This experimental set is for use

only by children over 8 years.

D. Because children’s abilities

vary so much, even within age groups,

supervising adults should exercise

discretion as to which experiments

are suitable and safe for them. The

instructions should enable supervisors

to assess any experiment to establish its

suitability for a particular child.

E. The supervising adult should

discuss the warnings and safety

information with the child or children

before commencing the experiments.

Particular attention should be paid to

the safe handling of crystal growing

chemical and its solution, and the use of

the kitchen stove.

F. The area surrounding the

experiment should be kept clear of any

obstructions and away from the storage of

food. It should be well lit and ventilated

and close to a water supply. A solid table

with a heat resistant top should be

provided.

G. Substances in non-reclosable

packaging should be used up (completely)

during the course of one experiment, i.e.

after opening the package.

Accompany your child during the

experiments and provide help when

needed. Make sure there is no ﬁre risk

when heating water on the kitchen stove!

And be careful to prevent the sodium

acetate crystal salt from coming into

contact with the skin, eyes, or mouth

while experimenting.

It is also important to keep the

sodium acetate powder, solutions made

from it, and especially the ﬁnished

crystals from getting into the hands of

small children. They might mistake them

for candies and put them in their mouth.

The ﬁnished crystals should be stored

in a cool, dark place. Direct sun and warm

heated air could melt them.

The blue dye will color things very

intensely and may cause stains that

can’t be washed out of clothing. Keep all

tablecloths, curtains, and carpets away

from the experimental area.

The work area should not be in the

kitchen — chemicals should be kept

strictly segregated from foodstuffs

and kitchen appliances. None of the

containers or equipment used for growing

the crystals should be used in the kitchen

afterwards. Please be sure to get all

necessary materials ready before starting

the experiments.

We wish you and your child a lot of

fun growing crystals!
