I could have “invented” the Pet Rock...but I didn’t.
Those were fun, fun to look at in their little cardboard boxes. I never purchased one. They came out about the same time the Chia Plants were introduced.
Around 3 years ago, there was a simple spinning toy introduced on the market. This toy became immensely popular with both children and adults. Some sort of spinner.
The name eludes me. Anyhow, you don’t hear much about them anymore.
