Onions, Electrolytes, and Apple
These are three things most households have: an onion, electrolytes, and an Apple iPod.
What do the three have in common? Well, it turns out that the three can work in harmony to give the iPod a battery charge!!! Don't believe me? Watch this (while the narration is boring, what you will witness will more than make up for it):
No more being on the road and realizing, "Shit! I forgot my iPod charger!" Now you can get an iPod charger at any supermarket around the world for only a couple of bucks, and when you're done with it you can cook with it!
