Launch A Snot Rocket
Gross? Yes. But far less nasty than using your sleeve while running.
STEP 1 TEST THE LAUNCH
If you try this without enough buildup, you risk an epic fail. Lightly inhale through each nostril. Can’t breathe comfortably? You’re ready to blow.
STEP 2 AIM AND FIRE
In one swift motion, seal the opposite nostril tightly with the pad of your finger, rotate your hips and shoulders toward the direction of fire, inhale through and then close your mouth, and finally exhale in one swift blast through your nose. Now breathe easy.
