Actually, I'm just toying around with words. I'm not going to give you a signal or message that passes below (sub) the normal limits of perception. Instead, I'm going to share with you a "cool" way that Aaron was learning about "sublimation" today in science class.
He was able to witness the process of sublimation by watching dry ice subliming. Super "cool" idea. So cold in fact that you'll need gloves to handle it because dry ice is so cold, it will burn your skin.
Normally, a solid changes first to a liquid and then to a gas as its temperature increases. Some substances, like dry ice for instance, skip the liquid state and change directly into a gas by the process of sublimation.

That demonstration of sublimation was nothing less than sublime. :)
