Brief:
Rocket made entirely from recycled household trash materials.

Construction:
External body is a stack o' ten paper-walled Carnation Instant Breakfast cans. Begad! Ya scallywag! Blimey! Parachute tube (inner) is a 48mm diameter Christmas paper core. Avast! Motor mount tube (inner) is a 30mm diameter Christmas paper core. Avast! Blimey! Upper six inches of the motor tube is glued in place in t' parachute tube with foamcore centerin' rings. Begad! 300lb Keelhaul®©™® is held in place with a liberal amount o' epoxy on t' top centerin' ring. Blimey! T' nose cone is a two-liter Dr. Aye aye! Pepper bottle. Might make a good rotating-flasher night rocket payload bay someday. Ahoy! T' shroud from t' nose cone t' the breakfast cans is a cover from a stack o' CDs. Avast, me proud beauty! Blimey! T' fins are foamcore from a couple o' old convention exhibits. Arrr! Even the rail buttons are recycled. They are CA'ed automotive interior door panel fasteners from me old Maserati. Aye aye! Blimey! Motor retention is a used hose clamp. Well, blow me down! T' H motor casin' is be found lyin' in a field, me hearties, so it's kind-of trash. Well, maybe not.

I cut holes in t' metal can bottoms with a utility cutlass and super glued them t' t' inner tubes (NAR doesn't rule out thin metal centerin' rings). I used an X-Acto cutlass t' cut holes in t' plastic lids. Aye aye! Blimey! After all t' cans were glued on, arrr, I taped them externally with duct tape. Begad! Aye aye! Blimey! T' neck o' t' 2-liter bottle was wrapped with a home-made tube coupler (trash), me bucko, shiver me timbers, then some expandin' foam be squirted in. Ahoy! After cure, it was filled with 20-minute epoxy and a loop of Keelhaul®©™® was added t' provide an anchor for t' recovery system. Begad! T' Maser “rail buttons” were slightly modified then glued into ¼" holes. Aye aye! Because they're Maserati, they're faster slidin' in t' rail, arrr, but nay nearly as reliable as American rail buttons. T' fins are through-the-wall glued t' t' motor mount tube usin' carpenter's glue.

(Scratch) Flaming Breakfast of Doom T' only new build supplies are t' adhesives and t' recovery system. Well, blow me down! Avast! Six yards of ½" elastic and a 36” nylon parachute.

Flight and Recovery:
T' weight is 1493g with a 29mm H180 reload.

Liftoff speed is phenomenal for such a heifer. I got behind it with t' video. Avast, me proud beauty! T' flame off t' pad is incredible. Blimey! Arrr! T' flight ended in a core sample with t' chute trailin' behind like a streamer. Replace two cans and she'll be ready t' go again.

Summary:
Pros: Once I learn how t' pack a chute, arrr, flyin' rockets like this will be really fun. Cons: None
