Visitors "travel through time" with a host playing several characters: from the Future, 1900, 1945 and 1999. Visitors answer questions in a quiz about other people's predictions of future technology, and then are invited to make their own predictions.
This is a stage presentation, designed for audiences of 11 and up, intended to give a broad overview and introduction to the subject of nanotechnology. The talk attempts to answer three basic questions about nanotech: How is It New, What Can It Do, and Do You Care?
Presenter puts Mentos candy into soda to create a soda fountain. This is a dramatic demonstration of the effects of surface area.
This demonstration isn’t heavily focused on nanotechnology,but can be a spectacular finale that you add on to other nano demos like Intro to Nano or Surface Area. (It’s probably best as a substitution for Alka-Seltzer, rather than being performed with it.) It’s also just a crowd pleasing demo that briefly mentions nano.
