I have never heard the method popping, nor has some of the other people I talk to. I do let my snakes rummage around in a bathtub of water to soak and play around, more so my anaconda. What I do after shes ran around in the water for a bit is I take a towel and I put it under her neck and once her head is past my hands i'll close my hands and let her wiggle through, completely drying herself, and sometimes getting some dirt or color from the cypress mulch off.
