The latest ‘Balancing Act” challenge got me thinking of a project I did about 8 months ago which is a mechanical toy crocodile that spits out marbles that were loaded in the back of its head. The principle is that the jaw keeps opening and closing when the marble drops through the hole in its mouth to the trough-like base. The bird in the back acting as a counter weight, brings back in position to release anothe marble. Its too brilliant an invention to be my own, but I’m sure it has ancient origins. It was a real challenge, and great fun to make and play around with. Here is a link to the youtube demo. http://www.youtube.com/watch?v=vcaE9nIQhlQ
Thanks for looking.
