Challenge One-shot glass is filled with water and the other one with whisky.

The challenge is to get the whisky in the glass that has the water

and the water in the glass that has the whisky in it without using

any other containers including your mouth.

 

You need two identical shot glasses.

1 non-porous piece of paper, like a playing card.

Water and whisky of your choice.

 

Place the non-porous paper on top of the shot glass of water.

Turn the paper and the water shot round carefully.

 

The paper will stay attached to the shot easily.

Now place the water shot, glass and paper on top of the shot of

whisky, slowly and carefully, pull the paper just far enough out to

make a small opening between the two glasses. Water, being

heavier then alcohol, will flow to the whisky glass and displace

the whisky into the water glass.

 

You have just made the switch.

If you are truly skilled at this bar trick, you will be able to replace

the paper between the two shot glasses and remove the whisky

and put it back on the bar.

 

Please make sure that the opening between the glasses is very

small, as a large opening will cause the water and alcohol to mix.
