I am going to go the stealth route and suggest a pocket sized device, one that actually fits in a pocket with a Hookah tube that can be placed inside the shirt run down the arm and the mouth piece just around the wrist. You can actually look like you are thinking
View attachment 488188. On the device have a short air tube that looks like the end of a Bic pen so you can get air into the coil. Use Bluetooth to actuate the settings for adjustments from your phone, no concern over dropping the mod either, unless you get de pants'ed, you are good to go! And NO ONE is going to inquire as to what the bulge in your pocket is!


.....Stealth vaping at its finest!!!
Now for the story behind this idea.....In high school a buddy and I made a tube to drink whiskey out of a small bottle placed inside your coat. We just used a rubber stopper that had a glass tube in the center and attached a small rubber tube. It worked like a charm, we got to the football game sober and left wasted and no one had a clue how we got smashed!
