I played with one of these 55 years ago during the summers of my youth. I loved getting wet while launching these into the air. My 3 year old grandson got a similar thrill this week with this rocket. The package comes with 3 rockets which was a bonus. My only criticism is that the pump does not seem to be quite as sturdy as what I remember from before and it took a little bit of effort to get it to work properly. Probably best if an adult helps with the pumping and launching.
