The first thing is to eat the hamburger upside down. Because the thickness of bread is different from top to bottom, the bread on the top is usually twice as fast as the bread on the bottom, so you can stabilize the materials inside by turning it over. Moreover, when it is turned upside down, the lettuce usually placed on the top will change to the bottom, so that the lettuce will become a natural waterproof cloth, and the gravy of hamburger meat will not always penetrate into the bread below, making the bread wet and soft.
There is a very awesome TV program in Japan. This TV program sent three experts-one is a fluid mechanics expert, one is an engineering expert and the other is a dental expert-to study how to eat hamburgers most easily. Although they always spent four months and didn't send a paper at last, they did get on the show.
Simply put, they found that the traditional way of holding hamburgers with thumb and forefinger was wrong, so the stress was uneven. In order to prevent the hamburger from overflowing, the best way is to use force evenly-they recommend using both hands, with the thumb and little finger at the bottom and the other three fingers at the top. This method is also applicable to "super-high" hamburgers, except that the remaining three fingers should be held on both sides of the hamburger.
Finally, if you eat in public, you must have a good attitude and don't feel embarrassed, otherwise you will attract attention and be calm. Through the above skills and a normal mind, even in public, you can finish the "super-high" hamburger in a civilized and elegant way.
But to be honest, the above methods and techniques are only applicable to ordinary "super-high" hamburgers. If it is a very, very huge "super high" hamburger, I personally feel that I have only eaten a little, and there is no better way, but it is best to have two supports on both sides to keep the "super high" hamburger from falling apart.
