Thought process:

"I want a cold drink with some flavor in it. I know, a cold tea."

"Hm, this doesn't seem to be dispersing. Wonder why not."

"Ah! Brownian motion is lower at lower temperatures. I just need... a vibrator?"

(Amusingly enough, that did help me find what I was looking for. Someone had confused the office drink frother as a vibrator at some point, so I was able to find it. Seems to have worked.)
