Anyways me and my friends would like to build or possibly buy a custom launcher that will launch Rubber chickens.
These rubber chickens are about 20 inches long and in the center about 5 inches wide. They are nothing but rubber formed into an unusual shape (a chicken) they are filled with stuffing (Like whats found in a pillow or a Teddy bear) and then they have a neck that is about 5 inches long and have a plastic object inside which makes these things scream/squeak when you squeeze and then let go of them.
Here is a picture:

These are very "squishy" so i wouldn't know how you'd make a launcher so that it'd launch this.
So We want this launcher to shoot it pretty far, if possible be able to adjust it so it will launch it far but not so hard that if you hit somebody with it it wouldn't hurt them, and then another setting so it shoots so hard its ridiculously funny.
So maybe a football field length distance? i don't know...
Any ideas or suggestions or people I should contact?
please help,
Thank you!
