Hahn, an Australian brewery, is obviously in the wrong business.
Instead of focusing on crafting fine ales, it should be further
developing and commercializing this stabilizing arm that
guarantees you won't spill a drop when being jostled about in a
bar.  That is, if the arm was actually more than just a clever
visual effect appearing in a Hahn commercial. But the same
technology exists for video cameras, so there's no reason why it
couldn't be adapted for a night of partying. [YouTube via The
