Once a long time a friend had a DR, and we decided to give him a small foldable pool for the country (2*2*1 meter). I gave it. Then on the DR stumbled and decided to try this fancy immediately, right in the apartment, on the 8th floor.
We gathered, poured water, splashed in it all night, but then we got to know that now it needs to be melted somehow.
The whole crowd then exhausted for two hours, evaporated, and when there was about 15 cm on the water, some wise man noticed a traffic jamming at the bottom and pulled it out.
And the swimming pool was no longer inside, but outside... and all the neighbors below.
