A 9-volt battery is an amazing little device, but it's also pretty annoying. After all, you may have one on hand in order to start fires, but you'd be hard-pressed to use it to power any of your devices — they hardly fit anything these days! But with a little tweaking, it turns out that you can make this battery work if you put your mind to it. Check it out below.
This is a superbly awesome trick! It's crazy that within the standard 9-volt battery, there are just several more batteries ready to be put to work!
As you can see in the video, this is an especially useful trick for when your flashlight runs out of juice and you still have a few days left of your camping trick. After all, who wants to sit in their tent in the dark when they could be playing cards or reading the latest paperback?
