After washing the ware is often put piles. It is great way to save the place, especially when it comes to plates. And here the glasses enclosed one in another sometimes are difficult to be separated. It can be done, having remembered laws of physics and having put not physical, but intellectual efforts. objects.
Instruction
1. Hot objects extend, and cold are narrowed, this property of substances is known to children from the fifth class. It is possible to use it. Heat waters in pan and also prepare very cold water or pieces of ice. Place external glass on hot Wednesday. Put in internal glass ice and pour cold water.
2. After temperature influence has begun, carefully try to pull out one glass from another. Slightly unscrew it, but do not pull. If to try to extend sharply glass, then from differential pressure it can burst.
3. It is possible to try to grease glasses to reduce between them friction force. Pour on walls of a little sunflower oil and let's it flow for edges. After that begin to take out glass. Do it slowly and accurately, the way described above. Instead of oil it is possible to use liquid soap.
4. It is possible to try just to lower glasses in water, having completely submerged them. After a while liquid will get into space between them, and then at you it can turn out to take out one glass from another.
5. The reason that one glass has got stuck in another also does not want to be chosen, is that between them the zone of reduced pressure was formed. Already small, it will decrease even stronger as soon as you begin to take away glasses. Therefore it is quite difficult to disconnect them. One original way would solve problem, but it is almost not feasible. It is possible to bring glasses to the area with reduced pressure, for example, on the high mountain. Then they would disperse from ease.
