Why is ketchup so hard to pour? - George Zaidan

View full lesson: ed.ted.com/less...
Ever go to pour ketchup on your fries...and nothing comes out? Or the opposite happens, and your plate is suddenly swimming in a sea of red? George Zaidan describes the physics behind this frustrating phenomenon, explaining how ketchup and other non-Newtonian fluids can suddenly transition from solid to liquid and back again.
Lesson by George Zaidan, animation by TOGETHER.

Unless the container is made of glass.

[@rayjohnson67]

[@smaklilu90]

the intent of this video is not to solve the problem. but to understand the properties of non-Newtonian fluids which is still a mystery on some part of it

[@doscruz1840]

true!

[@GameFlazh]

Wait... You don't have ketchup in a PLASTIC bottle? It's so much easier... It's easy to control how much ketchup you want on your fries since all you have to do is squeeze is to get the ketchup out and stop squeezing to stop.

[@hubril7921]

We have it put in a tube

[@kaoru1540]

that's not good for the environment, so factories usually use the glass ones.

[@panagiotisgeorgiou3263]

i dont think large factories care about the enviroment that much anyway about the glass or the plastic i prefer plastic as it is easier to pour out ketchup at the amount you want but the thing is that i find ketchup in glass bottle waaaay tastier. Same with coca cola in the glass it tasts better than the metal one or the plastic one , actualy i believe that everything stored in glass is better than plastic

[@MrWolfheart111]

The plastic leaves a strange taste in the ketchup after awhile... dont you find that?

[@lawrenceoliver105]

+Wolf Heart because plastic can produce chemicals when heated or stored for a long amoun of time

[@SplooksBwooks]

I remember being curious HOW ketchup got OUT of the bottle, so I faced the open bottle side near my face, so I could see how it got out. However...as said in the vid, ketchup is very hard to squeeze out, and can almost never have a perfect amount squeezed out.... 😐 In this case on my eyes and not my French fries...

Put ketchup in those plastic containers with tiny hole where you squeeze the bottle and the ketchup easily flows

[@LL-ip5mm]

Yup

[@KhOrganization]

I thought this was everywhere but in Canada it's in plastic bottles not glass (as the video said it was glass) so you just squeeze the bottle a bit and it comes out perfectly fine.

[@want-diversecontent3887]

CS:GO player Not everybody has a squeeze bottle.

[@cynTH95i]

I love learning random stuff like these! Thanks *TED-Ed*

[@TheAMG63driver]

I have had great success with a hybrid approach. Tap the bottle opening firmly on two fingers at a 30 degree angle. This not only aligns the tomato cells, but it allows for air displacement in the bottle as well. I have tried this with varying levels of ketchup in the bottle. There is still a percentage error maybe due to brand or age (evaporation) or other environmental factors. When all else fails, the less tedious option may be single serve ketchup packs that are fresh and squeeze out easily. Generally speaking. ... If there is a will, there is a way.

[@PuffyRainbowCloud]

In Sweden, this is mostly never a problem as our ketchup bottles are almost all plastic. Thus, we can apply force very easily (by squeezing the bottle) and the tiny opening allows for a relatively controlled amount of ketchup to come out just how we like it (most of the time).

How to ketchup fries: 1. Try to get a short amount using so much force 2. Let it pour out on its own 3. Shake before opening 4. Dip your fries in ketchup 5. Put ketchup on one fry and spread it to the others 6. Forget ketchup and eat it with mayo (I reccomend this)

Since plastic squeeze bottles are bad for the environment, and glass bottles make it hard to get the sauce out, the secret is to put into glass jars, and then take it out like you would with jam or peanut butter

[@theshyskeleton]

This is my favourite ted ed video

[@hqrwey]

The guy that started to destroy the tomato at 1:52 seems to be a master at cutting.🔪VS🍅

[@CatherineKatswell]

i usually tilt the bottle a bit, and pat it from the bottom of the bottle. always works for me.

[@alkasaket379]

3:20 I just saw that yesterday on action lab shorts!! *what the he-* !?

[@jakerpelman]

Tilt the bottle 45 degrees, tap gently at the middle of the curve on the neck.

[@TheTigero]

It's really not hard... Hold at just under a 45 degree angle and slowly tap. It just has to do with breaking the suction (letting a bubble of air in to displace some ketchup).

[@maejiang6197]

The CC for this video actually works!

[@Keywork55]

I'm also a ketchup pro but i would never dream of pouring it directly on fries, you have to keep the ketchup separated from the fries until you eat them!

[@nneoma4472]

Don't you just hate it when you pour ketchup and water comes out so then you have to close the bottle, shake it, then pour again?

[@zoneoftechrules5715]

HAPPENED TO ME

[@NotASovietSpy1]

same with mustard only worse

[@BariumCobaltNitrog3n]

2:54 you can't squeeze a glass bottle. If you hold the glass bottle upside down at a 45 degree angle and smack the "57" near the shoulder (of a Heinz bottle) it will pour nice and smooth. Alternatively you can insert a knife into the opening while the bottle is inverted and a lovely flow will take place. But, yeah the squeezy bottle is best.

[@Dekunutcase]

This video make anyone else hungry for fries and ketchup?

[@Dekunutcase]

***** hahaha, yeah. Pretty much. I'll just go make homemade oven fries. mmmm

[@AlyxiSistahTweaky25]

[@birdsdaword]

Grab the bottle by the bottom and swing it around a few times. Good for jams and all kinds of things in jars and bottles .

[@Lutranereis]

Who pours ketchup ON their fries? All that would accomplish is soggy, messy fries.

[@karbon4te]

thats why you use a fork and eat them all at once

That's fine if you're eating soggy McDonald fries, but a waste of good crisp fries; from wherever you may find them.

The shake and pour is the best way, primarily becasue it mixes any extra water back with the mixture and requires no squeezing at all.

[@DrAlexandrius]

just have a plastic bottle, it's much easier.

It's hard to pour because manufacturers make the neck too narrow - and restaurants insist on keeping full to the brim. Slightly wider mouth, filled to somewhere near the bottom of the neck - and no problem.
