How to inflate the Origami Windmill or Smart Waterbomb

Here I offer some additional suggestions and a video with tips on how to give volume to the Origami Windmill featured in my previous post (designed by Philip Chapman-Bell). This toy is made with a circular piece of paper, and it’s a lot of fun to play with children.

Once all the folds have been made -as demonstrated in the video posted previously, rest the circular piece of paper flat in the open palm of your dominant hand.
Identify the straight folds as valleys, and the curved folds as mountains.
Methodically pinch and emphasize each valley-fold toward the center of the paper. Continue pinching the valley-folds as the paper begins to take the form of a cup, cradled at its base by your hand.
Once you have a loosely formed cup, focus next on the curved mountain-folds and begin to pinch the ends of each as well, one by one.
Now gather the ends of these mountain-folds as you rotate the origami windmill in your hand.
To form the flat section place your non dominant palm so that it gently touches the outer border of the paper and impart a gentle twisting motion. This locks the egg-shape fancy origami windmill in place.

Here are two videos to make this origami windmill (Be sure to watch them both!)
