Here is a narrated and captioned presentation created for Materials Day at the COSI science museum: COSI Presentation (14.4 MB).

To run the presentation, extract all three files (one .ppsx and two .wmv videos) from the downloaded .zip file into the same folder. Open ‘Gohlke_COSISTM.ppsx’ using Powerpoint, and it will play automatically. There is a five second delay before the narration begins, and slides will advance automatically. If the file does not open (on Windows), right click the .ppsx file, select properties, and then click ‘Unblock’ to allow the video to be played.

(Slide 4 adapted from Powers of Ten by Ray and Charles Eames, slides 10-14 and 17 modified from IBM, and slide 16 audio from the Ohio State University Marching Band.)
