Waterfall ice American coffee frenzied overturning? Netizens who are strong all their lives do not believe in evil!

I believe that friends who watch Douyin and Little Red Book have browsed the video of Challenge Waterfall Ice American Coffee!

"Wow! Take a good look! It's easy! I can! " So ready to move you began to place an order for ice cup mold, and can not wait to immediately freeze several ice cups, put them by the window, set up your cell phone, ready to shoot beautiful and beautiful waterfall ice American coffee!

But the reality is. After putting the ice cup on the surface of the water, it poured! The coffee was sprinkled all over the table before it could be put into the water before it was poured into the ice cup. It's not easy not to wear it and pour it into the water, boy! The ice is stuck to the clip! It is not easy to wear the non-stick clip and put it on the surface of the water in a balanced way, so that the coffee is not at the bottom! It's the side! Or someone else is slowly pouring coffee down, while yours is falling into the water one by one.

Under the challenge of netizens, the original beautiful waterfall coffee has successfully become a "thin ice American style".

Because it's so hard to succeed! But how can stubborn netizens stop because of this! So some "non-evil" netizens began to share the secrets of the success of waterfall ice American coffee! If you want the ice cup to float steadily on the surface of the water, and do not perforate so quickly after pouring the coffee, first of all, the walls around the ice cup should be at least 0.2mm thick and uniform, and the bottom of the ice cup should be at least 0.3mm and flat, so that the ice cup is not prone to imbalance and side to side. (additional small tips: after the ice is removed, it can be frozen back for 5 minutes to increase the hardness of the ice. )

If there are conditions, you can put crushed ice in the water first, and then into the ice cup, which can increase the balance of the ice cup on the surface of the water. On the other hand, the clip used for the ice cup is as dry as possible to prevent the water droplets on the clip from solidifying and causing adhesion after touching the ice.

After putting the coffee liquid smoothly into the water, pour it gently and fill it with a height of 7 minutes. Pour coffee liquid into an ice cup and choose espresso at room temperature or warm temperature as much as possible to avoid using coffee liquid that is too high or too low. The waterfall effect of using hand-made coffee is not so good! The last thing is to be quick and ruthless, don't hesitate! Because the ice cup will dissolve quickly when it is put into water, the wall of the cup will be thin and thin. So prepare the coffee liquid before putting it in an ice cup. After putting it into the ice cup, use a container with a spout to pour the coffee into the ice cup. The spout is designed to allow the coffee to fall evenly into the cup.

To put it simply, the uniform thickness of the ice cup and the use of espresso are the key to success. As long as the ice cup can float smoothly on the water surface, and then slowly and gently inject coffee, reducing the impact of water on the ice cup, basically can be successful! But there is no guarantee that the final presentation will be "waterfall iced American coffee" or "leaping thin ice American style". After all, it depends on the temper of ice.

We can't reason with the ice cup and ask him to be at the bottom of the cup when the hole is broken, and a small one. Why can waterfall iced American coffee have the effect of gradual spread, but ordinary iced American coffee can not even be layered? At this time, we have to open the physics books that have been sealed for many years. "Diffusion due to different concentrations of liquids!" Isn't it the same with iced American coffee? (I'm not finished yet!

Diffusion phenomenon refers to the transfer of matter molecules from high concentration region to low concentration region, and its rate is proportional to the concentration gradient. After the coffee is injected into the ice cup, it is perforated, and the small gap reduces the diffusion area of coffee and increases the concentration difference of the solution, so the high concentration of liquid falls vertically like a waterfall under the action of diffusion. If the contact surface of the solution with different concentrations is too large, such as pouring espresso directly into ice water, the coffee will quickly dissolve with the water because of its rapid diffusion, so it is more difficult to see diffusion / gradual delamination.

Why is Waterfall Ice American Coffee suddenly popular?

Perhaps some friends wonder why the waterfall ice American coffee can suddenly be popular, obviously it is a very common coffee drink, and everyone imitates it one after another. This is probably because these gaudy practices have brought coffee closer to the public.

Compared with the American coffee produced in the cafe, the making of the machine usually makes ordinary people feel that it is very complicated to make this cup of coffee. The emergence of waterfall iced coffee sends a very important message, in fact, making coffee can also be very simple. It can be made with ready-made espresso / instant coffee. These materials are readily available and do not need a machine. Everyone can easily make a cup of coffee pleasing to the eye.

In the eyes of some small partners, this is a common thing, but for those who have no contact with coffee / less contact with coffee, it increases the opportunity of understanding and contact with coffee. it also lets everyone know that iced American coffee is made with high concentration of coffee mixed with water, and you don't necessarily need a coffee machine to make it.

The success of a cup of coffee lies not only in the taste of the coffee itself, but also in the ritual of the coffee-making process that attracts people to pay attention to and buy coffee. Just like making coffee by hand, people will want to learn to make coffee by hand and are more attracted by the process of making it.

Nowadays, although the practice of a lot of coffee looks gorgeous or superfluous, it is precisely because it has attracted more people's attention. Also through imitation interaction, continue to narrow the distance between people and coffee, so that coffee has become more popular.
