So I want to build Mort some kind of tennis ball cannon, and started researching tennis ball cannons for dogs. They essentially propel a tennis ball (or potato, traditionally) a very, very long distance. I could see Mort being over the moon with excitement.

I might only get as far as a Pringles can variety, but if that’s all it is – fine. Plus I might not get harassed by the authorities when carrying around one of the huge launcher cannons at the local park. Not to mention the most obvious: me, dogs, and propane is potentially a very bad mix.

So today I researched my options, and there are many different kinds of launchers out there. Have you ever thought of building a DIY tennis ball cannon? If you haven’t, you might be interested by the end of this post!

The Pringles Can Launcher

Maybe the simplest option? I had to laugh at the first failed attempts. I could see me only getting that far.

Hairspray and lighter launcher

I might get this far (perhaps with a manual light option instead of the grill lighter button). Plus hey, it’s a great high-school combo of hairspray and lighters. That said, I’ll have to go with whatever is actually safe…

Something with propane and a gas gauge

This cannon is being used to launch potatoes, and I fear capable of inflicting real injury. But I don’t doubt that it could be adjusted for more tennis ball and less ammo without too much difficulty. Right? Oh who am I kidding – I would never make this launcher.

Compressed air launcher

A top contender in my books, but probably way out of my skill level: this launcher involves a bunch of PVC like all of the others plus a compressed air chamber. It’ll launch the ball so far that Mort might get his workout with one or two launches. Pretty sweet, right?

So what do you think? Do you see building a tennis ball cannon for your dog? ME building one? I’m not too sure, but perhaps I should leave it to the pros.

  • Hi, you have a wonderful site, and I liked the videos on how to build a ball launcher. I am afraid if I tried some of these ideas I would end up in the emergency room of my local hospital, lol I think I better stick with the old fashioned way..the most that can happen is I throw out my shoulder, but my dogs would just remind me that I have another arm that I don’t use much. :) Thanks

    • Haha! Yeah, I\’m totally with you on ending up in the ER! I think that it\’s pretty likely this \”project\” may end at the research phase and we\’ll also be sticking with the old fashioned plastic launcher ;)
