Bubblers are the bridge between a hand pipe and a glass bong. It is essentially a hand pipe or bowl with an elongated section at the end that holds water. The smoke is directed through the water causing a diffusion like the downstem of a bong. This allows you to get the smooth hits of a water pipe without sacrificing the portability of a hand pipe. Bubblers come in different shapes and sizes like the hammer, sherlock, sidecar, pendant, double and even triple bubblers. A hammer bubbler got its name from being shaped, as you might assume, like a hammer. It has a long straight section connected to the water chamber that looks like the head of a hammer. The sherlock is named for its resemblance to an old school pipe like the ones Sherlock Holmes is seen using. Sidecar got its name from the water chamber being set to the side of the main straight section like the sidecar of a motorcycle. Pendant bubblers create a fashion statement with your piece. It is created with the ability to attach to a necklace to it so you can have it ready when you need it. Lastly double and triple bubblers refer to how many chambers the smoke passes through before you inhale.
