A person who likes insects very much did such an experiment: he put the flea into an open bottle, and it jumped out immediately. When the bottle is covered, the Flea will still try its best to jump out of the bottle. It keeps hitting the inside of the bottle cap. More than an hour later, he was still dancing like that.
Almost three hours later, it was still jumping, but it didn't knock against the cap any more. At this time, its jump height was about 1 cm from the cap, and it was the same every time.
At this time, the cap was taken off, but the flea didn't jump out of the cap. It still kept the height of the cap and couldn't jump out of the cap any more.
[Truth ]:
Life is actually a bottle without a cover. You can "jump" very high, but there are not many people who really "jump out of the bottle", because they always think that there is "covered with a cover ". Don't set all kinds of restrictions for yourself and lift the constraint of thought. We will no longer worry about the "bottle.
