Powerful snowmobile
With this turbocharged(涡轮増压的) snowmobile, getting over snow and ice will be snow problem. The snow Crawler snowmobile is designed with two skis under its front end. Below its back end is a pair of tracks, or rubber belts around a set of wheels. Inside it's heated, so jump inside, start up the engine, and listen as the wheels start to turn the tracks. Each track is designed to grip (抓住)slippery surfaces easily, allowing the snow-mobile to move over them without difficulty. Let it snow!
Floating furniture
It's easy to fall asleep in the special bed. This comfortable sleeping place features a plastic, water-filled mattress (气垫)that's designed to adapt to the shape of the person lying on it. Simply kick off your shoes and climb onto the bed. As you lie there, the mattress will hug your body. Meanwhile, the water in the mattress will gently rock you from side to side. It is a similar feeling to floating on your back in a pool. The mattress even heats up to make you extra comfortable. Now that is a dream bed.
Smart insoles(鞋垫)
This might take shoes in a new direction. The Lechal company has created shoes insoles that "tell" wearers how to get from one place to another. How do they work? Put the insoles into your shoes. The insoles are built to vibrate(振动). They are also connected wirelessly to your smartphone. Pull up the Lechal app on your phone and type your destination. The app uses GPS to map out the quickest path for you to walk. Every time you need to take a left or right the app signals the correct insole to vibrate so you know which direction to turn. That's amazing.
