Floating Egg

When you perform a trick, so often it is the patter that makes the difference and connects to the key point. Look at the following trick and see if you can adapt the patter to make your key learning point.

The audience sees three identical glasses of water set up on the table. You also have three eggs on the table.
Ask for three volunteers. Have each of them hold an egg. While they are holding the egg ask each person to direct his or her thoughts to the egg. Person 1 - Think about something else that is neutral, not happy, not sad.
Person 2 - Think negative thoughts. Person 3 - think really positive thoughts.

When they have been thinking for a minute or so, ask each person to put his or her egg into a glass. (you show them which glass)

Person 1 egg will hover in the middle.
Person 2 egg will sink to the bottom
Person 3 egg will rise to the top.

Make your key learning point.
So, wanna know how to do it? It's all in the water in the glass. The sinking egg is in a glass full of plain water. That's easy enough. The rising egg is in a glass that is super-saturated with salt water (test it out). The hovering egg is the tricky one. Fill the glass half full with salt water. Then tilt the glass and slowly pour in plain water. Be careful not to mix the waters. Test this one out until you have it.

So, see how you can adapt this trick? What if the main point was that someone or something was always sitting on the fence, then you would emphasize the neutral egg part. Just think of all the options around creating this trick into something that works for you.
