Cool! I want one!👍👍👍
A friend has a Hop Rod that he has tried several times to get it to work but didn't. Finally he took it to someone to rebuilt it but everyone is afraid to try it because of a rumor that it can go 20 feet high.

If you crawl through enough old issues of HOT ROD magazine you can find a gasoline powered pogo stick made by a California car artist and borderline nut-case inventor, VonDutch I think it was, and a rundown on how well it did/didn't work. I suspect this is where the 20 foot notion came from but I don't remember just exactly what the effect was--20 feet with rider or 20 feet after it had thrown the rider.😆
