Caffeine is America’s favorite drug, bar none. And while we’ve extolled the culinary and social aspects of coffee over the years, sometimes people don’t have time for a leisurely cup of joe and just want a quick fix.

Today Ben Yu, 21, one of Peter Thiel’s 20 Under 20 fellows, and his partner Deven Soni, have introduced a patent-pending form of caffeine that you spray directly on your skin. (This is not to be confused with Aeroshots, another novelty energy booster that is a powder you spray in your mouth.) The marketing materials claim that caffeine diffuses through your system more gradually through the skin than through drinking. Plus, at $15 for 40 doses, it’s wayyy cheaper than Red Bull.

Yesterday morning, I tried it.

6:15 am: It’s my morning to get up with my toddler daughter. She is super psyched to be alive as usual. I am moving a little more slowly.

9:20 am: I miss my morning coffee. Cold brew from Brooklyn roasters Oslo with milk and two packets of raw sugar. Instead I take the four-inch-long atomizer and deliver 4 sprays to the inside of my left wrist. The foamy liquid delivers no residue on the skin. I sniff–no aroma whatsoever, let alone a rich, roasty one. Sigh.

9:27 am: My eyes pop open like Betty Boop’s.

9:43 am: Whoo-hoo! The rush is a little bit disconcerting. Despite the claims, it feels like I drank my coffee very, very quickly. The tiny bottle contains 40 doses, 160 sprays. It’s recommended not to take more than 20 sprays in a day, but it would be pretty easy to overdose with such a small bottle, or if you just lose count.
