Ever remember them weird contraptions that work similar to the domino effect but have inanimate objects keeping the contraption going instead of dominoes? No, what about the incredible Honda cog advert? Either way, these contraptions are called Rube Goldberg machines.
This Rube Goldberg machine however, is quite different, appropriately titled 'Power Of Optics' it shows the machines being dictated by magnifying glasses. It's almost hypnotic to watch.
