>Simple stick stabilized rockets work out well for small pyrotechnics, but don’t scale well. If you want bigger bangs and larger bursts in the air you need to get more payload up there. A larger rocket, with a few pounds of excitement at the front end, would require a stick 20-30 feet in length; not very practical.
En essence, rocket like designs are less stable, less predictable, and more complicated.
It is hard to have something simpler and cheaper than a ball.
