rockets
the cub scouts made rockets out of cardboard tubes and water bottles. one of the scout dads bought the launcher kit thingy. it was a whole lot of fun not even spoiled by rain. garrett's rocket was nearly as tall as he. it didn't fly as high as other rockets for obvious reasons. i flew many model rockets when i was kid. so i know a wee bit of rocket science. b's and g's rockets made very pretty flights. they when straight up, arced over, and came straight down. they had large rigid fins and weight in the nose. many of the other rockets flew out of control. or floated back down sideways. the fun ended when the rocket with the last of the nozzles got stuck in a tree. ah well. ben and i spent quite a bit of quality time designing a rocket we'd name homesick angel.
