My toddler loves sensory play with beans, rice, oatmeal and more. We added this nice addition to her sensory play - the milk jug with a tube on it. I just rolled a piece of cardstock, taped it closed and then duct taped it to the top of the milk jug. I also cut open the side of the milk jug so she can get all the beans back out. It just takes pouring one step further - they mystery of not seeing the beans for a moment intrigue her and then the beans make a wonderful noise when they drop into the milk jug. She also puts pom poms down the shoot - they fall quietly to the bottom.
For some reason the older kids always pick up this milk jug, turn it upside down and pretend it is a weed wacker or a leaf blower! Kids have wonderful imaginations.
