In addition to pulling the ring, how can you open the cola can?｜ Play seriously

When everyone is opening a can

Have you ever encountered such a situation?

Unexplicable hard work

The pull ring is broken

experiment equipment

Bid cup, canned cola/beer, chopsticks

experiment procedure

To knock on the blackboard, pay attention to safety, don't hurt yourself ~

In the hot weather, I helplessly watch the cola without the pull ring.

Don't worry, just need a chopstick, you can still drink cola!

Rap the chopsticks at the opening of the cans of Yilai

After about 30 seconds

The cola can is automatically opened

We speed up friction

It took only 12 seconds this time

Just open the cans

UI

The cheats of this method lies in "fast"

Xiaobian before because the hand speed is too slow

After rubbing for 5 minutes, the cans of Yilai have not changed

After mastering the method

It's almost batch of tanks

Call other friends to be faster than anyone's hand ~

Original understanding

It can be seen from the above figure that the interfaces of the cans of the cans are upward, which shows that there must be some changes in the internal, and the lid is opened.

Both beer and cola contain a large amount of carbon dioxide. When the chopsticks are rubbing at the interface, due to the friction, the local temperature is increased, so that the carbon dioxide gas is swollen there, thereby opening the aluminum sheet above.
