Molasses killer and molasses catcher are the most common names for this accessory. Generally speaking, the molasses catcher prevents the syrup from leaking into the vase. Why is this important? After 2-3 sessions, water in the base will still be clear, and the shaft will not get soaked in syrup from the previous bowls. The catcher is a container with holes placed between the bowl connector and the bowl. The juice leaks out of the bowl and runs down the molasses catcher’s walls, and accumulates inside the container.
