hair gel + food coloring = great OT/sensory play (add in color and letter/sound recognition and spelling for older kids who still need the OT) Used this for my preschool class.they loved it.just make sure you tape them shut or they will pop them :)
Play Create Explore: Baby Oil Sensory Bags = baby oil, food colouring, a little bit of water, glitter, objects to find (smooth). Put in ziplock bag and duct tape for leaks and little fingers who would like to open it. ((or a heat seal bag))
