Spoons are the classic handheld glasspipes that you imagine when you hear "hand pipe", and theygenerally contain four main parts: a mouthpiece, a bowl, a neck, and a carb.The mouthpiece gives you a place to inhale from, and the bowl is where you packdry herbs. The neck is the long tube that connects the mouthpiece to the bowl,and the carb is a hole on the side of the bowl that allows for the control ofairflow. This control of air allows you to decide how strong your hits arewhile letting you moderate the speed at which you inhale smoke.
