My invention
My invention is a flying car. It is fast, convenient and green!
The flying car has four wheels and two wings. It has a top speed of 300km/h. You can go to farther places in a shorter time.
It can run on land and fly in the air. If you shout “fly”, the car will turn into a plane in 30 seconds. Then you can fly in the air. You will be as free as a bird.
Instead of petrol, the car uses solar power, so it will not pollute the air.
My invention will help people live a better
life in the future.

Checklist
My invention
I've designed a pair of multi-functional shoes which is very useful, convenient and green.
It is in the shape of a colorful racing car with four wheels. Besides, it’s made of nano materials, with the help of it, the shoes become light enough to walk so fast that it is easy to save effort.
As you can see, it can be changed into a pair of roller skates if you shout 'Transform'. And the wheels can be folded up into the bottom of the shoes when you don’t need them.
Instead of batteries, it is green to use solar power. What's more, we can control it through our voice by AI technology.
I hope that my invention will help people walk comfortably and easily in the future.
