Hi, Dawn 6/5/2018 My model, Pin-Less Pinwheel, diagrammed in OUSA Convention Book 1988.Page 243, was inspired by the Blow-up Rabbit, so I count it as a cousin of the Waterbomb.
The short directions: Make rabbit-ear folds on each flap of the Waterbomb base. Crease the open end firmly horizontally as high up as comfortable. Blow into the hole to inflate the model. The result is a pyramid with 4 vanes. Put a pencil in the hole, blow, and watch the Pinwheel spin. If you use a straw instead of a pencil, blow into the straw and send the Pinwheel flying into the air. I must have posted something about this to the list long ago -- in an email file from 2002, I find this lovely message from the late Dorothy Kaplan: Dottie wrote: > I just folded the waterbomb base the regular way....stuck it on a barbecue > stick from the hole up to the closed point....sort of spread out the > four sides of the waterbomb North East West and South without blowing it up > and blew.
