boy drinking a glass of waterYou’ll need a couple of volunteers for this experiment, but it’s totally worth it. Make sure you’ve got your science journal to record your results.

Prepare 12 cups with liquid – 3 should have plain water, 3 should have water with sugar, 3 should have water with red food coloring, and 3 should have water with red food coloring and sugar.


Label the cups in such a way that only you will know what is in each one.


Get a few volunteers. Tell them that in this experiment you will either be giving them water or punch. (Really you are giving them sugar water, but that’s basically all punch is.)


Give each person a cup, ask him or her to drink it, and then tell you, based on taste, if they had water or punch.


Record your results, and compare it to reality. How many people guessed wrong? Did these people’s drinks have anything in common?


What’s Happening: You will likely see a version of the placebo effect. People with red drinks will likely think they are drinking punch, even if they only have water with food coloring. People with clear drinks will likely think they are drinking water, even if their cup has sugar in it too.

    this would probably would be better with a blindfold .

  2. Susan Plott says:

    that’s kinda funny how they who have red water think they have punch even without the sugar, or how they think it’s water even if it has sugar.
