Tubes for Tennis Balls (alternative to FTC)

[RaZias]

I think that tubes for tennis balls are good alternative to FTC rockets.
(I am talking of those made of PET and not the ones made of PVC)

Interesting! Not very big (3 ball container: 7cm x 20cm, about 0.7 L volume) but obviously good to start out with nice straight sides. Can be spliced with existing technology, including nozzles from 330 ml which have close to the same diameter. The ones I have seen are quite thin walled but I guess they could be reinforced if required. Now all you need is access to your local tennis club's bins.

I had the same thought about a year ago but I think I may have had PVC cans because they held only about 90PSI. However I discovered something else you might find interesting... some brands sell the balls in a 4 pack canister! That's what? 33% longer! If you can find those in PET you will be able to splice a lot less.

The ones I posted are made of PETE, I don't know how many are there, I didn't counted.
