Boeing has been given a patent for a new kind of amphibious drone that's like something straight out of a classic spy movie. The aeronautics giant has a novel design for an unmanned aerial drone that can spontaneously convert into an unmanned submarine and go for a dive.
Kids' bikes are learning to grow as quickly as children. Designs like the Grow bike and B'kid expand in size to keep up with the fast-growing tyke, and the Wishbone bike keeps right on growing from pedal-free balance bike to pedal bike. The new Leg&Go bike does all that and even transforms to keep the ride going indoors and out in the snow.
