The elephant's toothpaste experiment! How you'll do it!

What to do:
Note:be sure to do this experiment on a washable surface, or

place the bottle on a tray.

1.  Hydrogen peroxide can irritate skin and eyes, so put on those safety goggles and ask an adult to carefully pour the hydrogen peroxide into the bottle.
2. Add 8 drops of your favorite food coloring into the bottle. 
3. Add about 1 tablespoon of liquid dish soap into the bottle and swish the bottle around a bit to mix it.
4.  In a separate small cup, combine the warm water and the yeast together and mix for about 30 seconds.
5.  Now the adventure starts! Pour the yeast water mixture into the bottle (a funnel helps here) and watch the foaminess begin!
