VAMPIRE SOAP

Warning--you'll look like you really have blood (okay, fake blood) on your hands with this experiment. But you will have a frighteningly good time!

You'll need:

a bar of soap
2 or 3 laxative pills, such as Ex-Lax
1 tablespoon of rubbing alcohol
small jar

What to do:

In a small jar, crush one or two pieces of Ex-Lax and add a tablespoon of rubbing alcohol

Rub some of the mixture on your hand and allow it to dry. Then wash it off with soap.

What happens:

The soapy water turns bright red!

Why this happens:

The laxative contains a substance called phenolphthalein, which turns bright red when it mixes with an alkali (also known as a base) like soap. Soap is made from boiling fat together with a strong alkali. By adding water you free some of the alkali, which is then free to mix with the phenolphthalein on your hand. of aging, harsh weather conditions, and pollution have turned the Statue of Liberty into the green color we see today.
