This is a fully functional potato powered clock. You just need to add potatoes, plug it in and it will work. No batteries needed, potato gives the power. Your kids will absolutely love this science experiment.
Possible school experiment to show importance of wetlands/riparian zones! This shows the importance of plants in our soil. Plants like trees and grasses help purify ground water. Without them the ground water gets polluted and harder to clean and drink.
Who knew that those tasty spuds can also do double-duty as an undercover battery? Believe it or not, the common potato has the capacity to create enough electrochemical energy to power a small digital clock.
