Review title: excellent value...
Product review: This rocket is a very cool device. I teach science and math and think this has great educational possibilities. You do need to be careful (adult supervision strongly recommended) as the initial speed of the rocket is considerable. The height that the rocket reaches is impressive. I've only tried the lowest pressure discs -with these the rocket reaches somewhere in the vicinity of 300 or more feet. I've done this with some of my students and they were very captivated by it. They commented that this is relatively trouble free (and has a good performance) compared to the rocket engines which require igniters. I agree.
