It appears these were sold in the 1950s and 60s.
Photo of real ones.
Youtube video which shows a few shots of them in action, but it's not the exclusive focus of the video.
Why did I not find out about these until now? My friends and I would have gone nuts over something like this. It couldn't have been more dangerous than some of the things we played on back then.
All I can see is a finger remover...
I fear for their hands.
That seems so fun. Obviously some potential danger, but not worse than a trampoline
That would have been about $150 in today's money and $70 for the extension track!
While this does come off as "we have rollercoaster at home" I will say that does look like a lot of fun
A similar, smaller one is still sold, obviously made from plastic now:
How much can I get in the class action?
So it's like a slide but with extra steps
When i was a kid I had a treehouse with a plastic slidet hat accomplished basically that, but without having to lug a vehicle uphill every time I wanted to play on it.
I've been subscribed to this guy, Paul Gregg, on YT for like ten years. He builds roller coasters in his backyard for his grandkids and goes over all the physics and design of them. They actually loop back around to the start unlike the one in this post where it seems like you need to haul the cart back up to the top. Very cool stuff
How does it stay on the track? Is it just wheels with grooves
That l thing looks like it can break legs
