The product includes an upright launch tube (12) adapted to be self-supporting on a horizontal surface (24) and a self-propelled aerial pyrotechnic device (14) adapted to be received within a fairly closely confined relationship within the tube in preparation for launch. In its preferred form, the tube (12) is slightly taller than the aerial device so that the aerial device is fully received within and surrounded by the side wall of the tube in the launch mode, except for a long fuse leading to the engine of the device and hanging out over the open upper edge of the tube. Except for a tapered nose cone (32), the device is substantially the same cross-sectional width along its entire length, including the lower regions thereof which are occupied by a plurality of stabilizing legs that support the device in an upright condition within the tube and balance the device during flight. The annular space surrounding the device within the tube is only slightly greater than that necessary to permit the fuse to extend up alongside of the device and out the open upper end of the tube, thus stabilizing the device prior to launch and during its progressive emergence from the launch tube.
