I used coca cola as a mild acid and sealant for a rubber barrel on a tumbler. It worked great as an industrial chemical.

All the advertising told my brain it was safe to drink. Yet, I was using it as an industrial chemical due to its high acidic nature. Which caused a heck of a disconnect in my brain.

I decided not to drink the industrial acid. It’s a bad idea. They use the extra acid to short your brain wiring, so you can drink something that’s too sweet to drink without an acid suppressing the gag reflex. That’s why it tastes so bad and sour when watered down.
