Arvind Gupta's science toys

Chitra arranged a brief visit to Arvind Gupta's lab/workshop on Friday. He designs science toys that can be made by street kids from easily obtainable Indian trash. His site is linked below. Here's a brief video I made that day:

He showed us the balancing nails trick (which they have at Explora in Albuquerque, too).

There was a flexagon with drawings of stages of evolution. In this video (linked from his site, to YouTube) he shows a food chain. Any four-part series could be illustrated on those, he said. (He told us who discovered/created this design first, too, but I don't remember the name, so if anyone does know, please leave a note.
