build a potato gun

unfortunatly ive been having some problems with getting the damn parts for it but when i do, me and my dad plan on building a second one. he says his way of building them and my way are really different so we weill both build one and see whos is better. im willing to bet his will be far better than mine because he has built some before. he also mentioned something about a lemon gun, i wonder if i get him to teach me to build one of those too, he said they’re much more dagerous hehehe

the title says it all, i didnt go to the store, so i still need to get the parts

ive taken an interest in potato guns lately, but ive always wanted 2 make one. im planning on getting the parts for it tommorow, or at least SOME of the parts. my mom keeps questioning me about it.
“this isnt something we’re going to get in trouble with is it?.. what are you going to shoot with it?.. where do you plan to discharge this thing?” blah blah blah… but i guess thats what mothers do
