Sidecar Bubbler Rigs are used for concentrates. These rigs feature a side-mounted mouth piece to reduce water backsplash. They also have a slitted downstem for moderate drag resistance and smoke diffusion. Each rig includes a 14mm banger. The “banger" is heated with a small hand torch for 20-30 seconds. Let the banger sit for a moment to allow the heat to spread evenly before adding concentrate to the banger.
