Luke, you just sired an idea, of which I am happy to be the dam (figuratively speaking):

To satisfy the lawyers, tour participants could sign "hold harmless" release forms (similar to the "ride at your own risk" release forms that rental stables use). In addition to conducting the rocket launch out back after the end of the tour, Estes could do something that manufacturers of radios, television sets, phonographs, and other devices used to do (and may still do) during tours of their plants:

If a tour participant wanted to buy a kit, it could be produced as he or she watched, so that that person could see how each kit is made, from start to finish. The kit could be personalized with a printed sticker with his or her name on it that would be affixed to the kit insert card before the bag was sealed (and since the tour participant wouldn't ever want to open that kit, s/he would likely buy a second example of that kit to build, thus resulting in two sales). Also:

My late friend Gary Moore had a phonograph that was manufactured for him during a plant tour, and even decades later he thought that was a nifty idea, as he had been curious as to how they were made. In addition, a lot of the "Picture, Picture" films (and later, videos) on the "Mister Rogers' Neighborhood" PBS children's television show also detailed how even the most mundane items (coaster wagons, tortilla chips, etc.) are manufactured, and Estes plant tours could also tap into that natural curiosity that adults as well as children have about how their belongings are made.
