Signal Flare
I was cleaning my garage the other day and found two road flares that are about 5 years old. Assuming they don't really "expire," are these the type of flares one might carry on a kayak in the event that you needed to signal a rescue craft of some sort? I know about flare GUNS, but what about these red flare sticks? Once you light them, they are water proof too right?
