The term cake refers to 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 500-gram cake is the largest cake available to the public. If you want the loudest, most effects, and color, then this is it.  500-grams is the amount of firework composition of powder total. Each cake will vary in size (9 – 350 shots), duration can reach up to over a minute, and types of effects can range from small to huge breaks. The top end of the price range and best value. Combined with other effects and you’ve created a huge show.
