"What?! Lemons?!" This morning a group of friends headed to the kitchen to do an experiment. We cut a little hole in the top of two lemons and added liquid watercolors, a drop of dish soap, and baking soda. Friends used droppers to squirt lemon juice on top. What happened next?
"It's erupting!!!"
"It's a volcano!"
"The red looks like hot lava; but of course it's not hot!"
