Glycerin-filled water pipes are really cool… Seriously though, they won’t expand and the glass won’t crack, when you throw them in the freezer. Why put your water pipe in the freezer? To cool down your smoke of course! By doing so, your hits will be a lot less harsh and you’ll have a much smoother experience. This is especially valuable for those of you with sensitive throats. Also, these water pipes look really awesome too. So come to your nearest Happy Habits® location and check them out today!
