If there is no air conditioning (6 photos)

In the absence of tin, my unit is assembled by carving on plastic bottles. It will take two or three bottles and a computer cooler (size chosen depending on the bottles, I had a 8 × 8), and in addition - a bit of paper and masking tape. It is necessary to make three parts.
Burn holes or a soldering iron, or cut out with a knife. The cone with holes is inserted into the glass.
The remaining piece is inserted fan
Secure it with tape, simultaneously closing the gap
Above the fan socket sets the paper, deflecting the air flow in the right direction
All "air conditioning" is ready. It only remains to put inside a glass cone inserted into the pre-frozen in a refrigerator ice, close all the fan cover and the socket and turn the power.
For most fans better not to use the power from USB, and battery "Krona" - besides, the construction of getting mobile.
Do not forget only drained from the lower "cup" melt water and enclose in a cone ice :)
