"Oh, hrmm, I didn't notice you should have said something. I would have explained."

Gesturing to the pile of sticks and jars.

"So, I am going to light each stick one at a time than spray it down with the contents of the jar while recording how long it takes to douse the flame entirely. The first jar had plain ordinary water, I will repeat the experiment twice more just to get an average and then move onto the salt water and there will also be a blend with bicarbonate. Each one will get three tests total and when I am done I will hopefully know if any of them is better at fighting ordinary fire than the other."
