And in order to secure for you the honorary title of Magus and Water Airbender, promise that you can deliver the paper to the bottom of any ocean (or even a bath or basin) without wetting it.

Let the present write their names on a sheet of paper.

We turn off the paper, remove it in a glass, so that it rested on his wall and slid down. Immerse a piece of glass upside down on the bottom of the tank.

Paper remains dry - water can not reach it! After the pull leaf - let the audience make sure he really dry.
Comment by Professor Nicolas: "If you take a glass with a piece of paper inside and look closely at it, it seems that there is nothing other than paper, but it is not, it has air.
When we turn the glass upside "down" and lowered into the water, the air does not allow water to get close to the paper, which is why it remains dry.
By the way, this property is used in a diving bell. "
