The tube is a paper tube, and the launching power is compressed air. By rotating or pressing a button to release compressed air, it will produce the impact of blasting, which will flush the colored sequins or petals filled in the paper tube into the air, producing a festive effect and becoming a prop to increase the festive atmosphere.
