I’d been told (in Chemistry class) that you pour acid into water because the splash comes not from the liquid you’re pouring from but from the liquid you’re pouring into. In your film the splash is clearly blue. Was that just a useless myth?
The wisdom of pouring acid into water, as I was taught, was that of there is some kind of splash or worse, like some kind of reaction causing an explosion, it will be of a dilute mixture. It also may be that the dynamics of a single drop are different from a pour. I will investigate.
Mixing acid and water is exothermic. You add the acid to the water so you can add a small amount of acid at a time, and let the solution cool down between aliquots.
