Materials:
2 Party Balloons
Flour
Funnel
Scissors
 
Using your mouth or a pump blow air into the balloon so that it inflates and stretches.  Let the air out of the balloon.
Using the funnel fill the balloon with flour.  Make sure to be holding the end of the balloon tightly to avoid a mess.  Stop putting flour in the balloon when it reaches the neck.  Don’t fill the neck.  Tie the neck into a knot to stop the flour from getting out of the balloon.
Take another balloon (it may be of a different colour, the final result will not be affected) and cut most of the neck off using scissors.
Stretch the second balloon over the first one as a second layer.  The second layer will help prevent the dispersion of flour all over the place in the event a hole would appear.  Enjoy!!!
