Think you know what it takes to fly a hexacopter?
Play this simulation to learn how force, torque and angular momentum all help hexacopters hover, move and turn.
I am the first to admit that I have never gotten the holidays quite right. Whether I’m late shopping for gifts, mess up my contribution to dinner, do something embarrassing at a holiday party or hang all the decorations crooked, something always seems to go wrong.

Next door to A2 Wind Tunnel, where cyclists work on reducing their wind resistance like in this video, is a larger building, another wind tunnel. But this facility, called the AeroDyn Wind Tunnel, is not meant for bicycles. It is meant to test cars, either for NASCAR, land speed competitions or drag races. Several NASCAR racers, including Dale Earnhardt Jr. have brought their cars to this tunnel.
