By completing the Fruit battery Science Experiment Project with your child, let your child experience the mystery of science, develop your child’s imagination and hands-on ability, and make your child more interested in scientific experiments.
Read the instructions carefully before building the project to avoid damage to the electronic watch or to prevent the LED from working.
Fruit selection：we suggest you use fruit with more juice, tomato will be your first choice, if you choose lemon and orange, please insert copper and zinc tablets in the same petal flesh (there is a membrane between the different petals that will hinder the transfer of electrons), as far as possible, insert copper and zinc tablets all the way into the fruit.The LED lighting effect is more visible in dim environments.
