We have had a few inside days over the holidays so I have had to come up with ideas to entertain Mima. One successful creation that was used all day was this flying fox. It was from a childhood memory of a cable car I made as a child and loved.
It is so simple, you need:
tape (I used a small amount of tape to reinforce the holes where the twine threads through the box)
From the start of the journey to their destination make sure the twine is one a steep incline and nice and tight. Hours of fun, whoosh!
