SAN ANTONIO – Hello parents, teachers and students!

Are you looking for something fun to do at home that has a little bit of science behind it?

Make Your Own Volcano

Here’s what you’ll need:

• empty soda or water bottle
• hydrogen peroxide (3%)
• active yeast
• dish soap
• warm water
• food coloring

Procedure/Instructions:

• Pour 1/2 cup hydrogen peroxide solution, 1/4 cup dishwashing soap, and a few drops of food coloring into the bottle. Swish the bottle around to mix the ingredients.
• Set the bottle some place where you won’t mind getting wet foam everywhere.
• In a separate container, mix a packet of active yeast with a little warm water. Give the yeast about five minutes to activate before proceeding to the next step.
• When you are ready to do the demo, pour the yeast mixture into the bottle. The reaction occurs immediately upon the addition of the yeast.
