I found this curvy object at a yard sale and found out that it is a hummingbird mister. You attach a hose to the end and mist comes out of the top to attract birds. It looked like a ring stack to me. I cut the rings out of detergent bottles and got some pretty nice colors. The stack is very stable when on the floor or table. I love how people are willing to stand to do this but it can also be done while sitting if the person can reach that high. I made some rings with large holes to be easy to put on and some have smaller holes so that they have to use both hands to push it on. Some individuals gave up easily when they had to work to push the rings on so this is a good activity to encourage persistence since it is a lot of fun to watch the rings coast downward. The visual stimulation is attractive to some individuals on the autism spectrum.
Some individuals were challenged to motor plan how to stabilize this thing on the table while getting the ring on and then needed to learn to let go of the tube so that the ring can travel all the way down.
Attaching the containers to the bottom of the mister is optional.
I have goals for many individuals to increase time engaged in repetitive tasks and to raise their arms above the head. This activity works on these and many other goals. I just wish that I had more of these bird misters and at different heights because some individuals couldn't reach it. In any case, it was a good yard sale find and the sellers generously donated it to me after I explained how I would use it.....
