Fun with colors today! Color wheels and color mixing fun with pipettes, which are just mini turkey basters (who knew!). I made the watercolor paint by uncapping markers and letting them soak in tiny cups of water. What a fun hands-on way to remember what colors can be combined to make secondary colors. **This 18x12x2 cake pan serves really well as a sensory tray. All the sensory trays that I saw labeled as sensory trays were pricey and only had one inch of depth. That's a recipe for disaster! I don't know about other kids, but we need two inches, people.
