Instead of buying tons of glitter all the time. We use colored rice. I bought a huge bag of long-grain white rice at Sams, Costco, or BJs (who knows). I am guessing on my measurements because it's been a while but I think for 3 cups of rice I added approximately 1 Tbs of rubbing alcohol and 2 drops of food coloring. I mixed it really well until every piece was coated and then I laid it outside on a piece of wax paper to dry. Make sure to spread it out evenly and when it is dry store it in a contained. We used individual ziplock bags. Here is a picture from last February of us using it as glitter. We made a banner to hang in our dining room that said, "God is Love."
Another great use for colored rice is just to put a few colors beside one another in a bowl. Let your toddler feel and mix the colors. What a great CHEAP sensory activity!
