When disaster strikes, a clogged bong is the last thing you need. Fortunately, an empty cola bottle can be repurposed as a makeshift water filtration system for your vaporizer in a pinch. To make this work, you'll want to use the cap from a standard red bottle, which can be sourced from various online platforms, including Giorgio's grabcad library at https://grabcad.com/library/red-bottle-cap
