Set for growing crystals.

A Christmas tree was born in the forest, in the forest it grew. This is known to all. But who wrapped it in snow, let's see (!)
First, the routine: payment 28.10 - receiving 01.12 (which, in principle, is already not bad)). In Russia, the parcel moved without tracking.
The factory packaging of the kit is a foil plastic bag (? 10x15 cm) with printing of mediocre quality.

However, on the back, amidst all this brilliance andchaos you can already find useful information. First of all, this is an instruction for putting the kit into action, designed in the form of pictograms. A warning about the age limit of the toy (3+) and a notice of the possibility of recycling.

The whole set, in fact, consists of: two halves of a cardboard skeleton, a support cup and a bag of (saline?) Solution.

The cardboard base is stylized "under the Christmas tree". To give a touch of future crystals, the branches of the tree are covered with paint. One half is red and the other is green. The trunk, according to the idea of ​​the Chinese, remained untouched.
For fastening (holding) the Christmas tree at the bottom of the cup, a groove in the form of a cross is provided. In general, the design is simple, like three Soviet kopecks and does not require any tools or special skills for assembly.

And then ... I made a mistake, a mistake. The fact is that I inattentively studied the information provided by the manufacturer about the use and contrary to the recommendations “Pour [solution] on top” I just poured it into a cup. This led to the fact that the cardboard base was wet only to the lower branches.

This means that crystals subsequently formed only on the barrel and the bottom of the cup [error].

This situation did not suit me from the word at all. Therefore, it was decided to fix everything. I disconnected the resulting crystals from the base and folded them back. The workpiece is well moistened by spraying from a spray gun. And in the tank I added warm boiled water. Thus, the process was restarted.

A change in the formulation brought the expected results: almost the entire upper part of the Christmas tree was covered with crystals.

To a lesser extent on the surface of the trunk, more intensively on the edges of the branches. Also, part of the crystals acquired a corresponding shade.

+ price
+ kit self-sufficiency
+ educational component of the process (and its reversibility, by the way, too)
+ user manual in pictures, which means you do not need to know the language / bother with the translator
+ the possibility of recycling waste consumption)))
± relevant Christmas theme (all with the upcoming! Seizing the opportunity)
± indicated age limit
± there are no pictograms of precautionary measures (maybe or even most likely precautionary measures are indicated on the packaging by text, i.e. hieroglyphs)
± the chemical formula of the reagent is not indicated (note see above ... it may be the name of the substance in the text. The question is open. I can’t find out for sure)
- poor quality printing + glossy surface - make it almost impossible to translate text from packaging using the camera and Google translator
- it seems that the salts in the solution quantitativelystill not enough for the formation of the same voluminous and fluffy crystals, as in the seller’s photo. In the reviews for the product, a rather sensible idea sounded to fill one cardboard with two bags of solution. Most likely this will improve the situation, but will directly lead to a rise in the cost of the project.
Still, taking into account all the pros, cons and needles, I liked the toy. She is funny and revealing to illustrate natural processes.
Now goodbye. Be good!
