This book, by the side of the road in a free box with its eight inch square colourful pages, was brought home and –
one of those pages folded into a water balloon –
which upon inflating with one quick breath looked like this on top and like this –
on the bottom. Water was dribbled carefully into that hole and then –
the water-filled balloon was thrown onto the deck where it burst in a satisfying spray of water.
A water balloon game of tag on a hot summer day is fun and refreshing.
There are books on origami at the library with instructions on how to make the balloon; oodles of info on the Net like this one
Enjoy!
