Did not come so on

This crystal growing box was allowed our son who is age-exactly in the target group test. The enthusiasm for it kept within limits:
- Many utensils and ingredients are still missing. Empty jam jars (or at least equivalent) is to be found perhaps, but Jed has distilled water in the house?
- The experiments require planning and require a lot of patience, because they usually require one or more days. Although our son is likely one of the patient ones, which was quite annoying.
- The first experiment has then not work, nobody knows why.
- The safety deterrent For nervous parents enough: One experiment in a space in which neither eaten nor slept. If you have no basement, so there were only hallway and bathroom.

The chemicals contained are manageable, but at least you get away with it on 13 experiments. Furthermore, the set contains various measuring cup, a treasure chest, Gussfortmen and plaster and various small parts. This includes safety glasses - but why only one? It should take care of a parent always. Bad solved is also the opening of the chemicals tubes: There are a cover lifter that allows you aufhebelt the lid. Only one needs it so much power that there is a risk to distribute a large part of the powder on his pants.

Bound to a booklet guide not only describes the experiments, but also gives explanations. All parts of the box can be ordered even in the cosmos; as far as chemicals, one can also ask again at the pharmacy of their choice.

My recommendation only at very interested and patient children.
