A Coke bottle is filled with water. You turn it upside down, and the water stays inside! Then you take a match and push it into the bottom of the bottle neck – it floats to the top.

You can also stick a pencil into the neck of the bottle and stir it around. Amazing!

Now a spectator gets the bottle. It doesn't work for him! - Of course!

You can find interesting demonstration ideas and routines in the magic salt supplement to the magical world , issue 6/2012.
