Water in a sieve

Water in a sieve
We continue to explore the magical properties of water and the surroundings. Ask someone from the audience to pull the bandage and pour water through it. As we can see - it without any difficulty passes through the holes in the bandages.
Argue with others that can make it so that the water will not pass through the bandage without any additional devices.
Cut a piece of bandage
Wrap a bandage or a glass of champagne glass.

Turn the glass - water does not come out!
Comment by Professor Nicolas: "Thanks to this property of water as the surface tension of water molecules want to be together all the time and they are not so easy to separate (Here they are wonderful girlfriends!). And if the hole size is small (as in our case), the film does not break even under the weight of the water! "
