Earth Battery

My daughter goes to a homeschool charter where she takes enrichment classes and gets to socialize and we totally love it. Today was open house and some kids shared stuff they have been doing at home or in classes. This kid shared his dirt battery and showed us how it powered an LED light. I was kind of amazed. The earth really can give us everything we need.

If you are into emergency preparedness or just want a cool science project you might want to look into dirt batteries. :)
