Hi folks,
I was seeing if Aniline HCl could be turned back into Aniline by reaction w/ NaOH solution (spoiler: it didn't seem to work). I went about dissolving
a small spatula full of Aniline HCl into about 75mLs of filtered tap water. Upon addition, the Hydrochloride crystals silently yet very quickly zoomed
around the surface like they were propelled by some force. They quickly dissolved.
What's causing this? I added a thermometer and observed pretty much no temperature change. Is there another reaction taking place that I'm not aware
of? Gases being released? Wizardry? The Force? I dunno. Share your ideas, your guess is as good as mine!

Edit: Are there any other chemicals that do this too?

The slight changes in heat as the crystals dissolve probably provide a strong enough convection current to push the crystals as they dissolve. I'd
like to see this in action though
