Water cups on the tables can be a pain with little ones. Especially little ones who like to play IN the water. (Don't misunderstand us...we love waterplay. But during a painting lesson, sometimes it's better to remove the water distraction!)
We've eliminated the risk of a cup of water spilling all over someone's art work.
Often times in our preschool classes, our instructors use spray bottles to wet our watercolors while the little ones paint. You can saturate all the color cakes with just a few sprays. The paint is ready quickly, which is important for sometimes-impatient lil' artists.
If we have a smaller class and time allows, we let the artists spray their own paint palettes. Preschoolers love spray bottles.
These small bottles are from from Dollar Tree.
