Can you imagine a pizza box that turns into serving plates? A fan without spinning blades (旋转叶片)? A garden growing on a wall? Well, get ready to learn about those great inventions!
A Special Pizza Box
The green box is a pizza box that can be used again. It makes less trash. There are four plates on the top half of the box. People don’t need extra paper plates. The bottom of the box folds in half and can be used to hold leftovers. William Walsh invented the green box. His friends often ate pizza, but they never used plates. One day, a friend got some hot cheese on his shirt. Walsh gave him a piece of the box to use as a plate.
A Safer Fan
The electric fan was invented more than 130 years ago. It has blades that spin and move the air. A company called Dyson has invented a new type of fan. It is safer to use and it can be easily cleaned.
A Living Wall

One of his newest gardens is growing in a hotel in London, England. It has about 260 kinds of plants. Blanc’s gardens are unusual. The plants do not grow in soil. Their roots are connected to a type of cloth. Water is pumped (输送) through the cloth to keep plants healthy.
