Have you heard the term cake? A firework cake is a cluster of pre-loaded tubes fused together to create a spectacular mini aerial show. You ignite the starting fuse by hand or electronically, then stand back and watch. A 200-gram cake is the smallest cake of the cake category. 200-grams is the amount of firework composition or powder total. Each cake will vary in size (16-36 shots), duration (up to 40 seconds), and effects. Much cheaper than their parent categories of 350 and 500-gram. Which makes them great for single use, or multiple use, or add them together with 350 and 500-gram cakes to create a larger show.
