【 Figure 】 mythbusters (7) Can’t use a wiper when an egg is attacked?
[Car Guide] I believe many people have heard of a rumor on the Internet: robbers frequently attack the windshield with raw eggs in a certain place, and never turn on the wiper to spray water. Because the egg will solidify when it meets the glass water, blocking the view up to 90%. When you are forced to stop to clean the glass, the robbers take the opportunity to rob. A search on the internet shows that there are more than one million similar rumors.


When I first heard the news, I couldn’t help but feel a little scared. Nowadays, there are so many kinds of robbers’ tricks that it is impossible to prevent them. After many years, similar rumors do not seem to have subsided. Although there have been rumors in the meantime, they are still used to reporting that they would rather believe their mentality and be more careful. It’s the end of the year again, and it’s inevitable for everyone to visit relatives and friends and travel by car, and the old-fashioned safety issue has been tirelessly hung up. Today, we will solve the rumors and doubts for everyone through experiments.
● Experimental introduction
Experimental tools:N raw eggs, some of which are added with "mysterious substances"
Experimental environment:The outdoor temperature is 3 degrees Celsius, and the test vehicle travels at a speed of 20 km/h.
Experimental process:The effects of raw eggs smashing windows and adding mysterious substances during the day were tested in two environments: day and night.

Before the experiment, we should check the working conditions of wiper blade and glass water to ensure the normal function of the vehicle system.
Experiment 1: Ordinary raw eggs

We drove at a speed of about 20km/h, and the eggs quickly broke open after touching the windshield. At this time, we turned on the water spray and wiper, and a large area of egg debris was cleaned up, and there was no obvious trace after repeated times.
Experiment 2: Ordinary raw eggs stay for a while before cleaning.

According to the rumors in the network, we didn’t rush to clean the eggs after they were smashed, but continued to drive for a minute or two before turning on the wiper. Because the egg white part has solidified, although the cleaning seems to have a good effect, the glass still leaves obvious white marks after drying, which affects the line of sight.
Experimental summary: if you really encounter an egg attack, you can wash it immediately!
Experiment 3: Night Effect of Common Eggs

We simulated the first experiment again in the case of poor night line. Although it can achieve a cleaner effect after several times of cleaning, due to the poor night light itself, the inconspicuous residue will also have a great impact on the line of sight.
Experiment 4: Ordinary Raw Eggs+Mysterious Formula
There are also rumors on the Internet that people who smash eggs will put some substances in the eggs before they implement "work". We also conducted related experiments to find a "mysterious formula", which seems to have achieved the legendary effect on the Internet.


We also drove the vehicle at the speed of 20km/h, and the eggs smashed by the roadside were broken on the windshield. After turning on the wiper, most of the egg residues were removed, but some mysterious residues were still not completely removed. After several attempts, the effect was still not obvious.
Test summary:Although eggs with mysterious substances can’t be wiped clean by the wiper very well, it’s better than not. Therefore, to sum up, if you encounter egg information, you should clean it with a wiper in time to improve your sight.
The following is a video of the effect of using a wiper after an egg attacks the window during the day and in the dark.
