Lemon Volcano Color Fun
Make a colorful lemon volcano with things you probably already have in your kitchen. This is a great way to learn about the colors of the rainbow for younger kids, and it is also a little science experiment for older children.
food coloring (we used powdered food color)
dish soap (optional)
squeeze bottle (for the vinegar & to practice motor skills)
(Adults only) Cut open the lemons and remove the endings so the lemons can stand.
Use a spoon or spatula to poke into the lemon flesh in order to release the juices.
Add them all in a tray, as this activity is about to get messy. Add the food coloring to the lemons and mix them with the lemon juice.
Dribble a little bit of dish soap to each lemon. This is an optional step, but it will make bubbles bigger.
Sprinkle a generous layer of baking soda on each lemon, and there will be a small reaction immediately. In order to make the reaction bigger use a spoon and mix the baking soda further into the lemon.
To make it more fun for my 2-year old I added vinegar to a squeeze bottle and we added that to the lemons. Mixing baking soda and vinegar forms carbon dioxide gas and cause the volcanos to erupt even more.
