Stinky volcano experiment

Rain, rain, go away! Gosh, it's been raining and raining and raining around here. We are going to go crazy inside these four walls all summer if this rain doesn't let up. However, there was a 20 minute peek of sunshine one afternoon last week. I quickly gathered all the materials needed for an exploding volcano.

Materials:
paper plate
plastic cup
aluminum foil
baking soda
vinegar
food coloring

The kids gathered around and waited and waited for the lava to explode and, when it did, all I heard them say was, "Stinky! That vinegar stinks! Do it again, Mom!".


Directions:
After putting the cup on the plate and wrapping aluminum foil around it, place a large spoonful of baking soda in it. Next, pour just enough vinegar in the cup to make the soda begin bubbling up. If you want the foam to come up fast and drip over the edges, add more soda or vinegar. I didn't have any food coloring left over from our last science project so we kept the color to a delicious coke-float theme.

Hey, I didn't know you had twin girls! Oh, wait! That middle child who is only a nose breadth away from the stinky volcano is MY daughter. :-)

Great pictures.
