It’s basically a small plastic tub of some sort (you could use a yogurt or sour cream container) with a hole cut in it to push pom poms through (you can find pom poms really inexpensively at the dollar store or at Hobby Lobby).
Silas had so much fun stuffing these in. When he was done, he dumped them all out and started over again. And he’s done it again and again like that!
This simple activity kept him happily occupied for quite a long while during our homeschooling time this past week and he hasn’t seemed to lose any interest or excitement about it yet!
