I enjoy taking a coffee cup filled with 98 percent Dihydrogen Monoxide into a public area then placing the cup in a microwave oven.

I expose the chemical mixture for about a minute in microwave radiation allowing the Dihydrogen Monoxide vapors to permute the local environment. People notice a slight vanilla almond fragrance. The vapors are working!

The molecules are attaching to the nasal olfactory nerve ganglia. Another successful mission in a public venue, people exposed to Dihydrogen Monoxide unaware of the vapors except the flavor fragrance. Next experiment, exposing the public to dehydrated Dihydrogen Monoxide!
