This presentation contains all the slides related to a steam engine. I will recommend to download and view it because then only the hyperlinks and other additional effects will work. The whole ppt. is automatic....No need to use the "enter key" or "mouse click". just use the hyperlinks. Also there are three videos embedded in the ppt. They all will not be played as in powerpoint, videos are linked not embedded. So if you need the videos contact me at : firstname.lastname@example.org or email@example.com. Also there are some sound effects, keep your volume up while viewing it. Enjoy viewing.
