Talk about a rapt audience. They sat down and waited patiently for the show. What the preschool teacher learned from making a bigger volcano.....bigger is not always better. The vinegar didn't penetrate 2 cups worth of baking soda rapidly, so it was the volcano that kept plucking along with a burp and spill here and there. But it held there attention and was the cause of many a squeal.
What a sweet little memory though, right? So--when you do this at home because it was so much fun at preschool...add dishsoap and food coloring to the baking soda and vinegar combination. It should froth and foam like orange lava. But hey--when you're 4 or 5, everything is impressive--just sayin'.
