Bubblers are like bongs little cousin. They are usually used to smoke concentrates or wax. Instead of the typical dry-herb bowl that you see come equipped on a bong, you might see a quartz or glass banger. Bangers allow for higher temperatures and more even heat distribution to maximize your concentrate and wax smoking experience. Bubblers can still be used as a traditional bong. If you have a dry-herb bowl, simply slot it in and a bubbler will do the trick.
