I recently purchased this toy for my nephew and was really amazed how much smoke it produces with just a tiny amount of "Hollywood" special effects fog/smoke fluid and some double A batteries. Has anyone looked into using this fluid and wiring up a simple gizmo with a few small batteries to make a smoke maker for your aircraft. It looks like it could be rather simple and very light compared to other methods. You really have to see how much smoke this little toy makes..............Also, the fluid is non-toxic and is cherry scented.
