KENTUCKY (10/8/13) - Looking for a way to add a little science to your Halloween? If so, using a few ingredients from around the house, you can create Dracula’s soap.
• Rubbing Alcohol
• Bar of Soap
STEP 1: Mash two Ex-Lax pills in a small bowl.
STEP 2: Pour 1 tablespoon of rubbing alcohol into the small bowl and mix.
STEP 3: Rub the mixture of Ex-Lax and rubbing alcohol on your hands and allow the mixture to dry.
STEP 4: Use soap and water to wash off the mixture of Ex-Lax and rubbing alcohol.
When you washed your hands with soap, which contains a strong alkali, a bright red appeared. Ex-Lax contains an ingredient called phenolphthalein, which turns a bright red when mixed with an alkali.
