My reaction would possibly be blown away I would be shocked because I am using materials that are basic and not used for Rube Goldberg I think that there no materials I feel like you use every day items and make something cool I would be blown because were using basic everyday materials and making a simple task  and how you might look at these DVD’s  used to watch a movie but in Rube Goldberg vision you would think a machine using DVD’s to put a DVD in the player
