Unfortunately, playground spinners are rare nowadays, because they carry some risk, and therefore in a litigious country like the United States they carry some risk of a lawsuit against whoever is responsible for the playground. You can see the decimation of risky play since the 1990s in most American playgrounds. Figure 3.6 shows the most common kind of structure in the playgrounds my children used in New York City in the early 2010s. It’s hard to hurt yourself on these things, which means children don’t learn much about how to not get hurt.
