Here's an easy sensory table we created for our 2 and 3 year old friends... colored rice. We used white rice, added a little rubbing alcohol.
Add drops of food coloring. You can either mix it up in a bowl or put it in a Ziploc bag and shake. I recommend a Ziploc bag if you are creating this with the little ones.
Instant rice sensory table. Add measuring cups, shovels, farm animals or any items from your weekly theme.
