Love this simple cow. Make a cow head and wrap a white blanket around a shelf or furniture. Attach a glove with tiny holes at each finger below the blanket and fill with water. Add a plastic container and let children milk the cow.
fill a latex glove about full with milk and tie shut. Put a very small pin hole in one or two of the fingers and the children can actually milk your "class cow" just like a real cow! I tied the glove to a string which was secured at the top of the easel.
