How to play the electronic piano carpet the day after tomorrow

After tomorrow, the electronic piano carpet can be played like this:

First make a high platform with walls and floors, then spread two carpets on the floor, and then spread a third carpet. Then put the first carpet where it overlaps with the third one. Finally, delete the second carpet and the first carpet, and then you will find that the third carpet that can be deleted from the floor is still in the air. Of course not every time. The success rate is about 20%. Moreover, the height difference between two flying carpets can only be a low wall, and the breast wall can't jump. Besides, this flying carpet can't hold ammunition boxes and things like that.
