Video from filming the program "EXperimenty" Science Channel 2.0 h4>
The theme of the "water" and Anton set the task to show clearly how the water pipe breaks. Of all the samples, this option was the most spectacular in terms of filming. Certainly, in the real world in the cold pipes are broken not so hard. But on television this version looks much more spectacular.
I remind you about our books .
And the new year we are preparing a set of New Year's with our books, chocolates and packaging with a surprise. In store will be available from 1 December. In the meantime, I publish some photos:
A set will cost 2490r. I beg to express their opinion: New Year's gift: three books with experiments for children + + packing candy with a surprise
Great idea! Ready to buy. Okay, but candy is better to give separately. There is no point in this set. Only registered users can vote in polls. Sign , please. 109 people have voted. 51 people abstained.
