Hands on test: can rice save the soup machine| Love to play computer games - 上海419贵族宝贝-上海后花园1314-上海品茶网-阿拉爱上海

Some time ago Love to play computer games Published an article《 Can toothpaste repair scratches on mobile phone screen 》In the article, some netizens asked us whether rice could really absorb water from flooded mobile phones and save them. It seems that the mobile phone has been connected with water since its birth. It often falls into the toilet, is stirred by the washing machine or falls into the sewer, so a good mobile phone really becomes a "soup machine". On the one hand, the owner is struggling to buy a new machine, and on the other hand, he is racking his brains to save the "soup machine". Since netizens have requirements If you can, of course, you should comply with the requirements of netizens.

When I looked up the data, I found many such reports on the Internet, and even authoritative media reported that rice could save the "soup machine". Many netizens said that the experiment had been successful, and they thought that the method of rice "saving" the mobile phone in the water was very effective. Xiaobian suddenly felt that rice was really a divine product!

As the saying goes, "because of this, scientific truth", Xiao Bian discussed with his computer loving colleagues. They thought that if the protective circuit in the cell phone fell into the water and did not short circuit or suffer other damage, it could be saved as long as the water in the cell phone was absorbed, but could rice really absorb water? Well, that's just doing experiments.

In order to verify this godlike experiment, all the members of the Ainongji team took advantage of lunch time to cross three subway stations and bought back a bag of international rice in a large shopping mall!

Experiment 1: Water absorption test of rice

The first test was indoors. We clamped two paper towels soaked in water with coins, one directly in the air and the other in rice, to see which environment dried faster. The following is the test process:

The paper towels with marks A and B have been stained with water

We put the paper towel marked A into rice and the paper towel marked B into the air

An hour later, the edge of the paper towel buried in the rice has dried. Opening the coin, we can find that the part trapped by the coin is slightly damp, which indicates that the rice has strong water absorption to the position that can be directly contacted.

Continue the experiment, the paper towels placed in the air became dry after two hours, that is to say, the drying time of the paper towels buried in the rice can be reduced by about 2/3 compared with that of the paper towels placed in the air without treatment.

Experiment 2: Mobile phone measurement

From this point of view, rice does have a certain degree of water absorption, but there is still a big difference between mobile phones and paper towels. At the same time, considering that mobile phones often fall into the water and there is still water in the gap, can the rice be dried where the rice cannot reach? So Xiao Bian specially found an old mobile phone and soaked it in water.

Soaking···

Water mist appeared on the mobile phone screen. As you can see, the time was 9 o'clock on the morning of December 27 (I finally saw the true face of this machine with tragic fate). Next, we found a box that could be sealed according to what we said on the Internet, and removed the back cover to bury it in rice.

Bury the phone in rice and seal it

24 hours later (9:00 a.m. on December 28), the answer was revealed, and the water curtain on the screen was gone

According to the preliminary conclusion obtained in Experiment 1, the effect of being buried in rice for 24 hours is roughly equivalent to being put in air for 72 hours, From the above figure, we can see that there is no water in the mobile phone screen. In addition, Xiaobian can also start the machine normally after putting the battery in.

Experiment 3: Test of drying ability of rice and drying oven

Rice can absorb water, but is there a better way? This experiment is to compare rice with the drying oven. We find eight coins, fold four small paper towels and place them between two coins, and then use adhesive tape to stick the coins tightly to simulate the gap in the mobile phone.

First, the test object showed that the coins were stacked together

Fold the paper towel and put it between two coins

Glue two coins with transparent glue

Four groups of coins are glued under the ingenious hand of a small knitting. Come on, put a pose

Make identification

Put A1 and A2 into rice

Put B1 and B2 into the drying oven

At 8:00 in the morning, that is, 16 hours later, we will take out A1 and B1 which are respectively placed in the rice and drying oven

Open the tape and coin. It seems that the effect is not obvious

The effect is obvious. You can see that the paper towels in the drying oven are drier than those in rice

At 4 p.m., 24 hours later, we will take out A2 and B2 (haha, fresh)

According to the method in the morning, we made a stroke on the paper towel. Group A still has no obvious improvement

Final presentation

In fact, the experiment has been done for several days, and it is finally coming to an end, and we can also make an assignment to the netizen who proposed the experiment. The whole experiment verified that rice does have a certain degree of water absorption, and can also absorb water in mobile phones, but The materials of mobile phones are different now, If the gap inside the mobile phone is tight and it is impossible to dry the water inside, it is unknown whether rice has such a good effect on every mobile phone.

Xiao Bian has another question: Now everyone uses smart phones, which seems much more delicate than functional phones. Are you willing to bury your beloved phone in rice? I believe I will receive many negative answers. From this test, it may be better to put it in the drying oven than in rice. In fact, there are special camera drying ovens on the market now. Xiao Bian thinks that cameras and mobile phones are the same type of products, and the drying oven is also clean. The reason why rice rescues mobile phones that fall into the water is that Xiao Bian suspects that rice is too common in life, but who will prepare an oven for an accident?
