Gif reminds me of a toy I had eons ago. It was from Mattel or Marx, or maybe Remco. It was a WAC Corporal rocket with a second stage. You hooked it up to a garden hose on full. You waited a minute or two and then yanked a six foot lanyard which released the stop plug from the rocket. Off it went. First stage about 100 feet and the second stage double that. It was great.
