My daughter loves this! She was able to do the experiment herself at eleven years old. It was really cool. It works on potatoes, lemons, or in soda. The directions were clear. A well-thought out science/STEM toy that any boy or girl would love. Would be great for younger kids--if they have an adult's help, also great for older kids (including tweens or teenagers) who could do the experiment themselves. A great homeschooling addition.
