This is essentially a shoulder-mounted sling shot that shoots large homemade Nerf-type darts.
It can also be used to launch other things like tennis balls, golf balls, tomatoes, apples, and even raw eggs.
This is something I had been working on in the back of my mind for over a year, trying to figure out all the details. For some reason the challenge of making a homemade, self-contained, bungee-powered, multi-ammo launcher was incredibly intriguing to me. I had never seen anything like it, and thought it would make a great experimental project.
The finished product is by no means high-powered like a compressed air- or combustion-fueled cannon, but it still packs a decent punch for what it is, and has turned out to be extremely fun to play with.
Please note that most of the information and details for this project are contained in the photos in the form of notes (the little yellow boxes). If you plan to make one of these, be sure to study all the photos and their notes carefully.
Thanks for looking!

it's very attractive
I don't think an rc car motor has enough torque or power to pull back a bungee cord strong enough to launch a can of soda, no. But I'm not sure how exactly you're attempting this, and with what supplies. I'm interested to see how this all turns out though! Are you going to post this project when it's completed?
But man . . . that looks like it would do some serious ocular damage!
snow balls.
Also, how do you go about priming it? Do you just sort of reach up from the breech and pull it through?
I used 3/4 inch PVC for handle because kids hands are smaller, mounted by making a plug for tube, tapping plug and screwing it on barrel then pinning with small screw. The main tube for thera band is 1 inch with 2 tees, and mounted same way and handle. I did not have the size pulleys in article, but I did have the ones from my plane which are composite and very free, they are small, I am waiting for my thera band to try. The thera band is attached to back of barrel by a turnbuckle, here to this is an experiment I wanted to keep weight down. As for the hardware, i did not use the carrage bolts, I used pan head scews which have the square on head for locking in, bought these at Menards.
Please let me know what you think.
Those bands will be under a lot of stress, and they can really whip around and cause some damage if you're not careful. Also, make sure the keyrings you use for the bands are high-strength. I had a flimsy one basically "unfold" itself as I was retracting the ammo back into the barrel to set it on the firing pin. Out of no where, it gave way and sliced up one of my fingers and shot a dart pretty hard against my garage wall!
