For one of my engineering classes we are to put together a miniature Rube Goldberg. All I'm looking for are ideas for an end result. For example, pouring a soda, turning off an alarm clock, lighting a match, raising a flag, popping popcorn, etc etc. So if you have any clever little ideas that would be great and let me know. Thanks! Here is an example of one, in case you don't know what I'm talking about. http://www.youtube.com/watch?v=RouXygRcRC4 The end result of this really long one was to open the curtains. Mine is only suppose to last 15-30 seconds.
