BRILLIANT idea I saw on Pinterest!!!
Simply squirt paint into large Ziploc bags (and seal them.)
Put a white piece of paper underneath, then use painters tape to put it on the table.
This mom used 2 different primary colors in each bag to teach an older child about color mixing.
This is the perfect mess-free activity to keep a kid interested for a couple hours on a rainy afternoon.
Leave it taped to the table for as long as you want... Just stick it in a drawer somewhere if you are cleaning up for company- then take it out again later :)
Simple. Cheap. Mess Free.
My kind of activity!
