Inspired by a recent post by Teacher's Pet, I remembered a type of roundabout I played on as a child called a Witch's Hat. It was really a combination of a roundabout and a swing as it swung around and into the central pole. Anyone remember these? I don't recall seeing them past the early '70's as I believe they were banned after several serious accidents, although lacking any real data this may be an urban myth.
I don't remember ever hurting myself but I can see how it was possible! The photo to the left doesn't really emanate danger and it looks like there is a restrictor near the top to limit the amount of movement towards the central pole. The photo below is better and with no restrictor this was the type that probably broke legs!
It's a little sad that my kids will never know the thrill of playing on one of these - I'm sure they weren't that dangerous!
I should point out that these aren't my photos and I'm not in them - I might remember the Witch's Hat but I'm not that old!
