I regressed to my childhood this year, I laid them all out and stared at them all excited. I took my dozen 16 oz. rockets, pulled out the top part where the bologna color is, and stuck an m-80 in there, but first i frayed the fuse and stuck it down where the actuall rocket part ends and lights the next stage, then stuck the little plastic cone back on the top. It made lighting in the sky. those 16 oz, rockets sure have some lift.
