Foldin' a streamer creates more aerodynamic drag than a typical rolled up streamer. This allows t' rocket t' fall slower t' t' ground. It is used most often in competition style model rockets. It can also be used in t' Team America Rocketry Challenge (TARC) contest where you have t' have your egg capsule come down separately. Ahoy! In part one, you'll see how t' fold t' streamer accordion style. Blimey! In part two, arrr, you'll see how t' attach it t' your model rocket.
