A lemon battery experiment involves the useof a juicy lemon, copper coin and zinc nail to form a lemon battery. When four such lemon batteries are combined, they produce enough voltage to light up an LED (light emitting diode).
Need a light? Use potato power! With this science experiment for kids, learn how chemical reactions take place between two dissimilar metals and how to create voltage. This is a classic STEM activity thats sure to please :)
