All parents, or for that matter all purchasers of toys, know that

sinking feeling when you realize the toy works nothing like the

commercial, or the picture on the box, or what you or your kid

thought. But these air pressure-powered rockets purchased today at the science

museum, work incredibly well. My 11-year-old put the launcher

together in minutes, and we had perhaps 20 successful flights. The

highest went really high, maybe 500 feet. It was literally out of

sight.
