As long as you have liquid you'll have plenty of energy when you power up with these cool new NoPoPo Water-Powered AA Batteries. Just use the included eyedropper to fill up the battery with almost any kind of liquid, like water, cola, beer or yes, even saliva and urine! Yep, you heard that right, urine! I'm not exactly sure of the science at work here, but liquid instantly charges these innovative batteries for up to 10 years and they can be recharged up to 5 times each. Best of all, unlike most batteries, these are made from 100% non-toxic materials.
Isn't it a comforting to know that if you ever find yourself fleeing through the woods from some undead creature of the night and your flashlight dies on you, that it can be quickly recharged with a quick pee break? Good luck getting that into the little eyedropper in a hurry!
