I just learned how to make a towel whip - aka. a rat tail whip. Believe it or not, there's a technique to this skill.
I was watching TV while swinging around my wet hair towel and convinced Mike he should let me practice towel whipping while he sat in the recliner.
Not only did he oblige, he gave me tips and pointers to get the whip motion just right and get that satisfying snapping sound.
And after 5 or 6 tries I NAILED IT!
Right on his knee.
POW... he's now got a red welt on his knee courtesy of my rat tail whip and I've acquired a new skill I should probably add to my resume. He laughed and ouched at the same time while I did a victory lap around the living room.
