Hello,
I have the core from a big sheet of plastic sitting in my basement, and it is just crying to be turned into a rocket. It is 3\" inside and 3 3/8\" outside diameter. The end is a bit munged, but it looks like someone could get 48\" of length out of it. Pretty heavy - probably 32 oz for 48\". Would need a high-power motor to make it fly.
If anyone wants it, it\'s yours. Little too big for me.
David
