Smart Schoolbag	Forget to put the books you need into your schoolbag in the morning before you go to school? A boy aged 11 has invented a schoolbag. It tells you which books to bring. A small computer and a scanner(扫描装置) are fixed in the bag. As each book is put into the bag, it is checked by the scanner. If any book is missing, a message will be shown on the computer screen to remind you.
Weather Sweets	Can you eat weather? A university makes that happen. It uses a 3D printer to create sweets according to the weather information of a certain day. The shapes of the sweets are influenced by wind speed. The colours of the sweets are decided by temperature. The sweets act as a weather record of the day when they are made.
Sunrise Bed	It's hard for you to get up in the morning, isn't it? To help you get up, a company has created a "tool" — a sunrise bed. It wakes you up as the sun rises. Lights built into the bed turn on and start to get brighter and brighter. When the lights are fully on, soft music will begin to play. It will be louder and louder until you turn it off.
