Sensory Activity-Grinding Coffee Beans

My kids love the aroma of fresh whole coffee beans so I came up with idea of purchasing an old vintage coffee grinder for them to use. I really think the grinding is a great sensory activity providing some exercise for the upper body by using some good old "muscles" and coordination and the aroma of the beans provide a sense of comfort and a refreshing feeling. Holding the knob correctly helps with those fine motor skills.
