Brief
This is made from a 'Finger Blaster' foam rocket and be t' 4th-place winner in t' Boink rocket contest.

Construction
Initially, I decided that I was nay goin' t' buy a foam rocket t' enter t' Boink rocket contest. Aye aye! Blimey! Begad! Blimey! However, shiver me timbers, arrr, at only 99 cents, I just couldn't resist pickin' up a 'Finger Blaster' (by Kidpower, Inc). Begad! Blimey! Begad! Blimey! This foam rocket has a built-in rubber band and is launched, at t' name implies, by hookin' it onto your finger, pullin' it back, arrr, and lettin' her rip. Begad! Blimey! Avast! Blimey! T' aft end conveniently had an 17.Xmm hole and a rigid stop where t' back end o' t' rubber band is attached. Aye aye! Blimey! Blimey! Blimey! I decided t' make this entry a bit more complicated, arrr, so I constructed a aft ejection streamer assembly with an outer 18mm tube and an inner 13mm motor tube. Arrr! Blimey! Well, matey, blow me down! Blimey! This assembly was friction fit into t' rocket's back-end. Blimey! Blimey! Blimey! Blimey! T' streamer is nay shown in t' photo's, but is packed betwixt t' 13mm and 18mm tubes.

After tryin' t' simulate t' rocket on RockSim, shiver me timbers, I decided some nose weight was required. Blimey! After some head-scratching, I used one o' those lead fishin' weights that connects by feedin' in t' line and twistin' t' rubber ends. Ya scallywag! Well, blow me down! Blimey! Well, matey, I removed that rubber piece, ya bilge rat, shiver me timbers, ya bilge rat, extended t' rubber band on t' rocket, put t' weight on, ya bilge rat, and let t' rubber band contract. Ya scallywag! Begad! Blimey! T' weight retracted into t' rocket and appeared t' be solidly connected t' t' rubber band. Blimey! Begad! Blimey! Other than t' launch lug that I glued on, shiver me timbers, no permanent modifications were made t' this rocket! Blimey!

Flight
My first flight was t' be on an A10-0, me hearties, matey, just t' verify stability. Avast! Ahoy! It boosted straight up and as a bonus t' streamer assembly drag separated. Aye aye! T' streamer is short and only slowed t' rocket slightly, me hearties, so it still landed with a nice boink. Begad! Blimey! I actually liked t' drag separation, so me second flight was also on an A10-0.
