funny trick :p

This is from G. I. Taylor's film on Low Reynolds Number Flows. For the full video, search for MIT fluid mechanics videos.

i've pooped all kinds

1: normal

2: peanut butter

4: tacos

[Aryastis]

this is epic.

[danielosbay]

Looks like fluid simulation.

[Awesomesauce1717]

y'all need to be more appreciative of science and its many ways... I dont like those comments about bodily fluids. They are disrespectful and people really dont wanna read them! Just sayin'. If you have something valuable to say, go ahead. But until then, please keep your comments to yourself

[GiggalGriffin]

@Awesomesauce1717 woooooooo totally with you :D

[cracktober]

All I saw was periodblood mixed with diarrhea

[keropoklekor007]

3rd is like sperm

[BoredEmo45656]

number 4: UH OH DIARREAH!! XD 

[inbredmusetta]

i am honestly curious. what oils are less dense than water?

[ji553r]

cool videos keep it up man

[Armuotas]

Third one looks pretty cool, like growing inverted mushroom.

[DARKsonofCHAOS]

and number 4 looks like periods from a girls vagina

[killacross]

the red fluid stays the same...the clear fluid has increasing viscosity from left (highest) to right (lowest) so the fluid in the right container is most likely water...then oils of some type

[akary]

@killacross

do you know this? i suspect otherwise. the red fluid on the left does not even appear to accelerate noticeably when it leaves the faucet, and then it coiled up on the surface LOW Reynolds #. the fluid on the right becomes turbulent and mixes in with the clear fluid. Oil and water are immiscible and as far as i know, all oils are light enough to float back to the surface of water..

[LABESTIA12]

@akary Wrong, all oils are not lighter than water and therefore will go to the bottom

[jsteed5]

@LABESTIA12 You are incorrect. I am a chemical engineer (Ph.D) working for the largest oil company in the world for the past 30 years. Most hydrocarbon oils in the downstream business are less dense than water, therefore will float to the surface of water. The exception can be with heavy oils, such as vacuum tower short resid, which may have a specific gravity greater then 1 depending on how deep the vacuum is. This oil will sink in water, and will be solid at room temperature.

@jsteed5 SHAZAM!

[trident3b]

@jsteed5 may I contact you with a question regarding leak detection for oil pipelines?

[akuamakana]

number 4 is a girl leaking through a tube

[JDO658]

Number 1 looks simply like a person taking a shit through a tube.

[Clockworkster]

lol nr.1 is a ....looks like a toothpaste...nr.2 is an mushroom anchor (yes they use water resistance to stop) nr.3 is a jellyfish and nr.4 is a volcano cloud (in early stage) upside down

[Anti1gnorant]

lol watÉ

[narutosponge]

i dont get anything

[vidallaurel]

did the viscosity of the red substance or the clear substance change? or both

[XBUGMANX]

@vidallaurel definately just the clear substance was changed...

[aaaaabbbbbcccccd]

i understand. i see an upside-down sunset, mushroom, taller mushroom, and tornado =]

[dauticalnisaster]

wouldn't the density of water vs. the density of the substances also affect their ability to stay near the surface, and not spread out?

[Jsuarez6]

Yes. I think that in this experiment the objective was to show how fast the red fluid flows (according to its viscosity) in the clear fluid. After a while the fluids begin to mix.

[winterpeger]

Anyone who took a shit in a north american toilet knows this phenomina.

[hectorvrl]

very nice =o
