TUBES or SHELLS or MORTARS are single shot items that will fire a shell up to 25 meters in the air. At it's peak, the shell will explode into a burst of colour. They are quite spectacular. Sometimes they are shaped like a weeping willow or a peony flower. These are smaller versions of what you see at a professional show. There are also tubes that shoot comets - like a shooting star with a glittering tail and also mines which are giant fan shaped bursts up into the sky.
