Wandering around STP's site I came across a "pepper spray reliever:"

"UDAP's pepper spray reliever"

Wow! I could have used this on a backpack last summer the night I thought I was sipping from my .75 liter aluminum water bottle and I was really putting my lips to a can of bear spray that I'd screwed the trigger off of.

FINALLY, we have the equivalent of a "morning-after" pill when our 'bear protection' doesn't work as we had planned.
