I encouraged him to use all the space in the bin, including the inside walls.
Of course any kind of paint with young children will often turn to finger painting and because I wasn't worried about the messiness of this activity, I encouraged him to explore painting his hands with the various brushes.
Even though the paint was repeatedly swirled together, the complimentary colours blended into a beautiful shade of aqua green and was still appealing to use.
The paint was cool and felt so smooth and Caleb spent a long time exploring it.
This activity was fun and so easy to do! An easy way to save any pictures or printing done in the paint is to lightly press a piece of large paper against it and make a print of the work. This way children's experiences can still be saved for classroom display or portfolio use.
When we were done we simply washed the bin out in our tub. Any large water/tactile table would work well for including many children at once. Smaller bins could also be placed together on a table top with many different colour combinations.
