I’m going to sell “Ping Pong Ball Pumps”.
I’ll have them manufactured in Sweden because they are famous for pump technology.
note: I might have to design special shoes called “Ping Pong Pump Pumps” so the user can hold the pump in place while inflating flat ping pong balls.
double note: I may market a “ping pong ball patch kit” for balls with slow leaks. (basically just tape: but if people buy the pump and shoes, they will buy anything!)
triple note: Ping Pong Balls make more of a “dut dut dut” sound than a “ping pong” sound. I could be wrong; I usually am.
quadruple note: The Ping Pong Paddle business is a good “racket” to get in to.
