She was the same instructor who told us to how remember to add
acid to water, and not the other way around. She had a sign posted
in the studio, "Dump the acid in the ocean."
I learned a similar, but much cheesier, saying in Chemistry classes
that helped us to remember the same safety rule: "I think you oughter
add the acid to the water!"
It'd be less dialectically accurate, but you could spell it "otter"
and make a cute little sign...in your spare time
