Repair A Flashlight

This hack is similar to the battery solution in an earlier post. Basically, you can use aluminum foil to quickly fix a flashlight that might not be getting a connection. Sometimes the springs in flashlights get worn out and no longer tough the terminals on a battery. If this happens, you can use a bit of aluminum foil to fill the gap and restore the current in the flashlight.

Of course, you could probably use this little trick for just about any situation that needs a connection restored, but a flashlight tends to be one of those items that you don't realize is not working until you really need it.
