In this clip, I test how long it takes me to gag when I touch my uvula and the back of my throat. I mess with things back there with my two fingers until I can't take it anymore and start to gag. Tears start to to drip from my eyes and saliva runs all the way to my elbow before I quit. Then I do it a couple more times.

This is a well lit clip and you can see deep down in my throat and watch me move my uvula with my fingers.
