This video is only 1 minute 25 seconds and yet, by the end of it I had forgotten what it was meant to be about. Lost in learning! Lost in intrigue. Lost in the wonder of all that was occurring. It’s all physics. It’s a video which makes people want to know and find things out. On top of that, it is funny. It’s a carefully planned, well thought out , high impact lesson. It would have taken brainstorming, discussion, trial runs. There would have been a feedback loop and collaboration. It’s a video which arouses a lot of curiosity and engages the audience. A one minute video can do a lot!
