We're Ryan and Rebecca and we know electricity comes from a generator. The key to a generator is a metal coil that spins inside a magnet. Rebecca thought her pet cow, Goldie, could make the metal coil spin. We attached a rope to Goldie's harness. When Goldie moved forward she pulled the rope which turned the metal coil. But it took a lot of effort for me to get Goldie to move. She just didn't want to work! Do you have a better idea for getting electricity from a cow?
