It is like this when you really analyze fluid how to drink a grain-filled corn soup can drink without leaving grains

ByAkibubblet

"A fluid dynamics teacher said that if you squeeze a little under the drinking mouth of the corn soup with grain, you can drink without leaving the grainThat's why the way to make it easier to drink the last remaining barbecue when drinking a common grain filled corn soup can spread explosively on Twitter and the number of retweets has already exceeded 11,000 However, although it is easy to drink, it is easy to drink, but what kind of theory is actually?) Was introduced in a movie to make it easy to explain.

Fluid analysis of the way to eat corn potnage cones successfully - wealthy life with poor dexterity

I analyzed the fluid analysis method of how to eat cone of corn potage well. Mp4 - YouTube


"Fluid simulation of a method of eating corn of a corn potage can successfully"


"When you drink normally"


It is the grain of corn that is precipitating towards the bottom


Tobacco


I started to gather without flowing around the exit


In other words


"9 out of 28 grains remained"


"When recessed"


Tobasaka


"Two of the 28 grains remained"


So, for the time being, it is confirmed that "it is easier for people to dent"


And finally I went into the "consideration" "Why is it easy to get out?"


"No indentation - From the side (speed display)"


The speed indication is that the red part is fast and the blue part is the slow flow.


Anyway, I can not say that the speed of the leading edge is fast, anyway, the speed of the cone inside


The speed did not rise so much, stagnating like this


"There is a dent · From the side (speed indication)"


It is dented greatly


And check that the speed surely rises at the upper part of the dent


Moreover, not only that but also the speed rises even in the part that comes out


"Due to the presence of a dent, most cones pass through the fast flowing pottage surface, making it easier to get caught by the drinking mouth, and a swirl is created beneath the drinking mouth, pushing down the cone that tries to catch up, it is easy to get out It is becoming "


"I feel like ..."


That's why there is a reasonable basis for saying "If you squeeze a little under the drinking spout of corn soup with grain, you can drink without leaving any grain".
