I spent a couple of weeks on vacation recently, most of it in Houston, Texas. While there, I visited my sister-in-law in her preschool classroom. While there, I found....
A bin full of tops! They were large finger spinners, which had been made for the preschool by high school wood shop students, as their final lathe projects. I took a picture, and I'll try to include it here (although I don't get along with computers real well).
They were all made of similar wood, although I don't know what it was. The grain was open and coarse, and some of them were quite light weight. Most of them spun well enough, except for one, which didn't work well, at all. The one that spun the best is in my hand in the photo.
I loved that I was able to find tops, even while away on vacation....
