With all the advancements in technology, it was only a matter of time before science was (more) melded in with the holidays. One of the coolest ways I've seen it action has to be the flying mistletoe drone. It recently made a visit to San Francisco's Union Square and motivated the already cheery people into some loving lip-locks. Check out this short one-minute video and see if this doesn't get you into the Christmas spirit. All props and respect go to whoever was operating that thing. Great flying buddy!
