After an appropriate delay of time admiring my handiwork, when I was younger I would tie a golfball-sized rock (about 5cm) to a 10' length of string, then to the airplane...then would throw them both over a cliff.
The rock would accelerate faster, dragging the plane behind it...which of course would make it look like it's flying...for about 4 seconds, before impact.
Tank models were shot, as were the myriad 1/35 scale soldiers. Missing them caused dirt "explosions."
See? One can have several different levels of fun with models...it ain't just about sniffing glue (which I was warned against, many many times, by my parents.) I'd have never EVEN thought of doing that, I was so vestal.
