Paint (we used crayola washable paint)
Something to pop the balloons - I have seen darts being used, but we just used an extra thumbtack
Optional- goggles and a smock/poncho
Fill the balloon with paint
Pump the balloon to desired size and tie balloon
Attach balloon to canvas with thumbtack
Repeat until the canvas is covered.
E1 and I LOVED this project!! E2 did not want to participate in the popping of balloons, but she enjoyed watching her big sister.
