Earlier this weekend we saw Google present a very WarioWare-esque series of challenges in the form of a Chrome app that demonstrated the super swift boot up time of their new laptop. Here's comes another game, but this time it's presented within YouTube.

Unlike most similar attempts via the format, in which you watch a clip, and then chose another to move the action along (with this being the most popular example perhaps), Nexus Contraptions is a series of physics-based challenges, much in the vein of Fantastic Contraption.

Because I generally suck at Rube Goldberg machines, I am unable to get past the third stage, but I'm sure most will fare better. Test your wits here.
