Some years ago, I got the kids into launching Estes Rockets. Below is the Big Bertha, caught in slo-mo on my phone camera:
It’s rated for 500 vertical feet, which isn’t terribly high for these models. Its size and relatively low height allows you to really see the whole flight, notably when the rocket hits its apogee and the parachute pops out. Thousand-foot rockets are a blast (see what I did there?) to launch as well, but you can’t see as much of the flight path.
