In our lives, pockets can be seen everywhere, making our clothes beautiful and making life convenient. But once the pockets no longer fit, or there are too many pockets to handle, it becomes inconvenient. So I hope to invent an infinite pocket made of nanotechnology that can easily fit even an elephant and keep items intact.

When you want to put an item into the infinite pocket, you only need to untie the red rope on the pocket, and then say "stop" to the rope, and the infinite pocket will automatically open its big opening. Mouth〃, eat the object. When you want it to release the item, you untie the green rope, say "release" to an open place, and then you can take out the item you want.

One feature of Infinite Pocket is that it is anti-theft. You don’t have to worry about it being stolen. Even if the signal is poor, it can send information to your watch. Not only that, when someone else touches it, it will automatically turn on the fingerprint recognition or pupil scanning mode. If it does not match the owner's information, it will immediately and continuously sound a beeping alarm. As long as the person doesn't let go, it won't stop. In this way, the thief can do nothing about this bag. No matter how he tears, pulls or steps on it, the items in the pocket and the infinite pocket will not hurt a hair.

Infinite pockets can also be used to carry new year’s goods during the New Year. During the Chinese New Year, we often have to bring a lot of items back to our hometown, or after spending the Spring Festival in our hometown, we have to bring a lot of hometown specialties back to the city. This is when unlimited pockets come in handy, making long-distance travel much easier.

I believe that many people hope that life will become more and more convenient. The infinite pocket I want to invent can reduce everyone’s burden and travel light. Do you have any good inventions? Come and write about it too! Excellent Essay on My Wonderful Ideas in Fourth Grade 3
