So I was just going through my powders seeing if I needed to purge anything. Found a small sealed Sinclair powder measure bottle that had maybe 2 ounces of some vintage 93’ N130 that dried up like scorched earth. I unscrewed the cap which emerged a funky acidic smell of course. So then I added maybe 2 ounces of water and screwed the cap back on, figuring I’m going to flush the mixture down the toilet. Here’s where it got interesting, it made some noise and then the bottle swelled up slightly. I purged the bottle and filled it water.This crap is going in the ditch.
