When in doubt... build hell-for-stout!
He takes the hook... and the hook is set....I'll take that to mean "A penny and..." but FYI a penny weighs 2.5 grams. Prior to September, 1882 they weighted 3.11 grams, but most of those have enough wear by now to weigh closer to 3 even.
Since you've been successful with 2.5 gram pennies, you obviously can leave well enough alone (and don't need me to tell you that). But if you want 4.67 grams, go with a nickel (5 grams even) or a better yet penny plus a dime (2.500 + 2.268 grams). Do I get credit in the nerd pride thread for this?
As a handy mental reference for small gram weights, I like to think of how many nickels they would be.
"The first series of Indian Head pennies were minted in 1859. These pennies weigh 4.67 grams and are composed of 88% copper and 12% nickel."
So to summarize: A 2.5 gram penny and a 12 foot streamer = an even slooooower decent.
I never did a calc to determine how long it would take the streamer to drop. Maybe I can get a good launch video? Again, problematic with just me and the wife at the field. The rocket has a 28" diameter chute though, and with an apogee of 1030 feet it should be easy to see.
That's all assuming a straight stable flight. I know some folks are thinking with that big hammer head, a straight stable flight may be unobtainium. Who knows? It passed the swing test with "flying" colors. Only thing left to do is drop the "hammer", and light the fire.
