Discussion: This was by far our favorite liquid replacement, the unanimous winner of the Great Bong Experiment of 2016. If you're hoping to try this one, make sure the seltzer is chilled, fresh, and bubbly for optimal effect.
The first inhale is crisp and fresh. It almost tastes like the smoke has been textured. The carbonation actually changes the smoke to make it tingle in your mouth and throat, almost like inhaling Pop Rocks. We tried it first at room temperature, then added a few ice cubes. The chilled version was far and away the better choice. The ice cooled the smoke and the carbonation altered the consistency in a most pleasing manner.
Note: We consulted with a scientist to ensure the safety of this particular fluid. It was relayed to us that, in moderation, it is highly unlikely that this liquid would be dangerous. However, just for good measure, be safe and proceed with caution.
