One day I was struggling to grind aspirin for a face mask. My wrist was aching as I twirled the pill crusher back and forth, but after smashing the stuff for quite some time, the pieces still weren't small enough. Then I had an epiphany.
Aspirin dissolves, Doofenshmirtz.
I poured a bunch of aspirin into a container along with aloe gel. In no time at all the aspirin had quietly disintegrated. I gave it a final stir, and presto, my wrist was ache-free and my face was tingling pleasantly beneath the aspirin mask.
