How Do You Make A Potato-Powered LCD Watch Science Project?
If you think potatoes are dull, think again. Potatoes are versatile because they are an essential ingredient in food recipes, make salty snacks, can be used as craft stamps and can power a watch. They might be just what you are looking for when it comes time to do a science project. Like lemons, potatoes can power an LCD watch.
