Gatling Barrage (300 shots) by Cube Fireworks

Three hundred shots in roughly 48 seconds, built to look like a Gatling gun and firing like one. Red, green and blue pearls with crackling comets pour out in a continuous stream, fast enough that individual shots stop registering. The unit is 92cm long with a plastic spike moulded into the base, so it pushes straight into firm ground with no separate staking. Fire two or three in a shallow V to criss-cross the sky.
