I remember when manufacturers changed beer & pop cans from the straight walled design they had. I was crestfallen. Oh no! This meant that the tennis ball cannon were no longer practical from easily sourced neighborhood materials. For those who didn't grow up with them, they were a simple device. 7 or 8 cans had both ends removed and joined with duct tape (black hockey tape was traditional) one can on the bottom left intact, with a small hole in the bottom as a touch off. Lighter fluid (or hair spray?) was propellant of choice. A tennis ball was the perfect diameter.
