Arvind Gupta Toys
Arvind Gupta is an Indian science communicator who specialises in making toys from the sorts of stuff you probably have lying around the house. His website is full of terrific ideas and starting points, and his YouTube channel has hundreds of films like the one above.
Pretty much any of Gupta’s ideas could be used as starting points for SciCast films. In fact, they’re very similar to the things we used to do on CITV’s The Big Bang, which was one of the inspirations for SciCast in the first place.
