Doritos Flavor Shots are a breathing hazard! 

These are regular Doritos with packets of flavor powder inside the bags.  There are two flavors, "Atomic Chile Limon" and "Blazin' Buffalo Rush".  You pour the powder into the bag and shake it up to coat the chips.

The problem with this is that when you crunch them in your mouth, the powder aerosolizes and "puffs" into your throat, nose, and lungs, coating them.  You momentarily inhale powder, and have to cough to clear your lungs.

If you're going to eat these, wait awhile for the powder to settle and bind to the original coating.  I don't know how long that would be, and I'm not going to experiment.
