You will need:
Small Balloons
Darts (plastic if possible)
Large board and paper (or a large canvas)
Balloon Pump
Paint bottles (washable is best)
An old sheet
Drawing pins
You need to do:
Place a balloon over the top of a squeezey pant bottle and squirt in a small amount of paint
Use the balloon pump to add some air to the balloon
Tape your paper to a board or suspend your canvas, choose somewhere low enough for kids to reach
Attach the balloons to the canvas or board with a drawing pin (through the tied, twisted part of the balloon)
Throw darts and watch the balloons pop and the paint splat!
Let the art dry then mount and enjoy!
