The Trick

Set the cup of colored water and beans on a table in front of your audience. Use a separate, unlabeled cup to hold the vinegar. Tell your audience that you can make the beans in the cup magically start jumping around just by filling the cup the rest of the way with water.

Pour the vinegar in (the audience will think it’s water) and watch their amazement as the beans start jumping around in the colored water!
