My wife Trudy and I needed something to keep our two-month-old grandsons William and Sidney occupied when they visited us. So we made some mobiles out of things we had lying around the house. We used an old roll-on deodorant, washing liquid balls, empty drink bottles, a garden windmill and other bits and bobs to make a brightly-coloured fly and two hummingbirds. The boys were mesmerised.
