The droppers are excellent for developing fine motor skills- and once kids get the hang of them, they can't get enough!
Liam and Hanna use their brushes to explore the vibrant colors.
After a little while of painting on paper, I brought out a tub of whipped cream- Calling it "foam," amazingly kept them from tasting it! Similar in texture to shaving cream, whipped cream is a great alternative if you want something non-toxic (shaving cream doesn't seem very child- friendly even though preschools and children's art books often use it for sensory projects).
The kids were interested in squeezing out the paint themselves, so I offered them some watered down paint in different squeeze bottles for them to go at it.
Towards the end of class I brought out the spray bottles. These kids must have had some spray bottle experience- they were masters at squeezing the trigger.
