Taste the Rainbow from Fire Factory is a 25 shot, 500 gram cake with a run time of about 20 seconds. The published effect details are partial, but the format tells you the shape of the show: full power 500 gram shots, 25 of them, delivered in a dense 20 second run. It works well as a mid show piece, or paired with a second cake when you want a wider spread of shots across the sky.
