Pushing for Sensory Input

Here are 2 very different activities that both involved using a very large plastic container with a hole cut into the lid.Both of the clients have much anxiety and difficulty motor planning. the individual in the video is pushing golf balls through an opening and he had to use force to push it in. This gives sensory input while also developing hand strength.
The photos shows an individual pushing socks through the opening. He has to motor plan how to push to make them in to fit. The socks are filled with either sand, lentils or just plastic supermarket bags.
