Can you imagine surfing the Internet without lifting your finger? Do you want to know what it feels like to fly like a bird? Let’s have a look at some of the “Best inventions of the Year 2012”. Wing Suits The suit can make your dream of flying like a bird come true. Well, not exactly flying, but gliding(滑翔)through the air. Fliers wearing wing suits can glide one kilometer in about 30 seconds. But they need a parachute(降落伞)to make a safe landing because the suit does not allow you to slow down. Talk Gloves Do you often feel confused(困惑的)by the sign language used by disabled people? Here is the “helping hand” you need.
