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

Construction
Initially, arrr, me hearties, I decided that I be nay goin' t' buy a foam rocket t' enter t' Boink rocket contest. Begad! However, at only 99 cents, arrr, I just couldn't resist pickin' up a 'Finger Blaster' (by Kidpower, shiver me timbers, me bucko, Inc). This foam rocket has a built-in rubber band and is launched, shiver me timbers, at t' name implies, ya bilge rat, by hookin' it onto your finger, pullin' it back, ya bilge rat, and lettin' her rip. Ahoy! T' aft end conveniently had an 17.Xmm hole and a rigid stop where t' back end o' t' rubber band is attached. Well, blow me down! I decided t' make this entry a bit more complicated, so I constructed a aft ejection streamer assembly with an outer 18mm tube and an inner 13mm motor tube. Ahoy! Begad! This assembly was friction fit into t' rocket's back-end. Well, blow me down! 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, arrr, ya bilge rat, I decided some nose weight be required. After some head-scratching, I used one o' those lead fishin' weights that connects by feedin' in t' line and twistin' t' rubber ends. Avast, me proud beauty! Well, arrr, I removed that rubber piece, me hearties, matey, extended t' rubber band on t' rocket, ya bilge rat, put t' weight on, ya bilge rat, shiver me timbers, and let t' rubber band contract. Well, blow me down! T' weight retracted into t' rocket and appeared t' be solidly connected t' t' rubber band. Aye aye! Well, me bucko, blow me down! Other than t' launch lug that I glued on, no permanent modifications were made t' this rocket!

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