This is an awesome science experiment where you can learn about the importance of properly washing your hands with soap.

• Grab a medium-sized bowl and fill it half-way with water. Coloring your water blue with food coloring is optional but makes it easier to see the experiment in action.

• Grab a teaspoon of black pepper and sprinkle onto the top of your water.

  1. Be careful with how much you put in, putting too much might affect the outcome

• Dip your finger into the dish with water and black pepper. This will be your "Germ Bowl."

• Notice the black pepper stick to your finger. Why do you think this is?

• Wipe your finger clean and make sure there are no more black pepper particles on your finger.

• Cover the tip of one of your fingers with dish soap.

• Next, dip that finger into your "Germ Bowl."

• Why happened?

• Did the "germs" stick to your finger or did they spread apart?

Question: Why didn't the "germs" get stuck to your finger when you had soapy fingers?

Answer: When the soap enters the water, the surface tension changes causing the pepper to no longer float at the top.

• The water molecules want to keep the surface intact so they pull away from the soap carrying the pepper flakes with them

Question: How is this similar with how bacteria gets broken down by the soap as the pepper did?

REMINDER: It is really important to wash your hands with soap so that germs and other bacteria are washed off. This will help you stay healthy and safe.
