It is said that on a hot summer day when in North End. You might actually be able to smell the molasses.

[@mikeowen657]

I smelled it in summer 1960, and there was a faint stain on buildings abutting the hill

[@andipandi]

you still can...

[@atseatse]

andi pandi Where in the North End? I work right near the North End.

[@AngelaJeanBarr]

I may not have understood all the science, but I very much appreciate the computer simulation and the original photography. Very helpful in understanding how massive it really was. Thank you!!!

[@spin979]

Thanks for all the work. I grew up there and heard the stories for years. This really tells what happened.

[@weirdalfan1980]

Such a sticky situation

[@daniellbondad6670]

Warm molasses-Has the viscosity of chocolate syrup. Winter-chilled molasses-Solid

[@edwardmiessner6502]

Thanks for all the hard work simulating this disaster. I grew up in Scituate, MA in the 1970s and lived in the area in the 1980s & 90s. I visited friends who lived in the North End back at that time and remember Giorgio's Pizza and Bova Italian Bakery fondly. I have family who adopted 2 cats from the bakery and named them after it (Bova & Bee). Fond memories. Now in Boston, "as slow as molasses in January" is no joke! Edit: add stuff

[@dandelionveins]

Thank you, I had a hard time imagining the speed! Terrifying.

[@MrPeabody67]

Ingomar, could you do a Hope Slide simulation on of these days? It's the largest natural slide in Canada.

[@ingomar200]

Hello Cody, Yes, the Hope Slide might make a good target for simulation. I did publish a You Tube that features the Chehalis Lake (BC, Canada, 2007) landslide and tsunami that might interest you. kzbin.info/www/bejne/jmSvpodnobVjZsU Thanks.

A similar thing happened somewhere in Colorado in 1992 or so. Everyone thought it might be oil, but it turned out to be molasses!

[@elvastan]

It was in Loveland in 1990

[@anthonyharraden4709]

I grew up in a city about 25 miles south. Brockton, MA. Thank you for this video 👏.

[@jsdp]

Just want to say I love all of your videos :D Stay awesome!

[@documentariosvideosexplica6910]

I love your videos. I downloaded several simulations through your site.

[@bigaaron]

Just a suggestion: you may have more viewership if you add some sort of audio/voiceover so the audience isn't simply sitting in silence. Great videos otherwise

[@briansammond7801]

100% agree. Total silence was very off-putting.

[@liliya_aseeva]

Yes, I thought my phone failed:D

[@Kitty-hf6vq]

I second that, even some quiet background music could work too

[@carpii]

@@Kitty-hf6vq it was probably uploaded just for a presentation, with them talking over it

[@esf9827]

Coincidencially I am learning aboit this in science class because of the viscosity bit.

[@Weatherboy1102]

Please do the Johnstown Dam break!

[@cowsgrowontrees980]

Really excellent, informative video. Thank you for all your work

[@n00bicon4]

ingomar, would you please make a video of the Mosul Dam failure?

[@ingomar200]

Hello Fake Farmer, Yes, some call the Mosul Dam the most dangerous in the world. It is built atop slowly dissolving rock. A bad choice! A few months ago I did run a simulation of its failure... es.ucsc.edu/~ward/mosul-map.mov The simulation has not yet made it to the "You Tube" stage. Thanks.

[@wildearth3992]

Nankai tsunami please ?

[@Jay-yy9ol]

Nice work but very difficult to consume the visual information while reading the text.

[@jhhwild]

You should do a simulation of the The Johnstown Flood disaster.

[@chicenburger]

You should take a look through his uploads, he did one in 2010...

[@ParasaurolophusEwan]

What simulator did you use?

[@ginojaco]

@ingomar200 this is reminiscent of the London Beer Flood of 1814.

[@007jacquie]

★Excellent Educational Videos Thank-you!

[@zachtheobald3802]

Had it happened on a hot day, it would have spread much further and caused more damage.

[@Azhucabomb]

I wish I could have seen it in person!

[@Retravox]

just ignore The 7th

[@Retravox]

ingomer200 in the ~1970s* west virginia had one of the worst, if not the worst flood in its history caused by a collapsing dam. make a simulation for a video on the tsunami *couldve been earlier/later then the ~1970s

[@ingomar200]

Yes Thanks LegendCraft69 Gaming, That would be the Buffalo Creek Flood of 1972. 500,000 m^3 escaped. It might make a good video. That case seems very similar to a recent movie I did called Bento Rodrigues Mine Disaster.mov kzbin.info/www/bejne/oWGziIWferyAirs 70 million m^3 escaped there.

[@ytmndman]

How about the Chesapeake Bay impact and tsunami? Or Burckle Crater?

[@daniellbondad6670]

+ingomar200 I need to tell you that molasses is a shear thinning fluid,meaning that it gets thinner with more force. Considering the fact that it is 5 stories high,gravity would thin all that molasses for a while. Many science websites shared this. That is why it travelled at 54kph at the start.

[@ingomar200]

Hello Daniell, Yes, just how to implement frictional resistance to flow in this story is a matter of debate. Total frictional resistance is some function of flow velocity and flow thickness, F(V,H) Likely, resistance goes up as velocity increases and flow thickness decreases. One functional class of intrinsic resistance is shear thinning as you mention. Even within this class however you have a huge leeway in implementation of F(V,H). Keep in mind that you really want to simulate Total Frictional Resistance not just intrinsic viscous friction -- the molasses has to push air out of the way for example. There is an additional dynamic drag force here. I chose the total frictional de-acceleration equal to Const*(Flow Velocity^2)/(Flow thickness) with the constant adjusted to match the observed extent of the flow. This seemed to work well, but there may be other equally good choices. Regardless of details, one end member that everyone can agree on is the "no friction at all" case that was shown in the video. This gives the 35mph initial flow rate, but clearly contradicts observations of flow extent.

[@cesarlopez6368]

100th anniversary of this disaster

[@ciro6849]

The video is great and interesting, but you could have add some audio as well. It is too boring this way.

[@Elocian]

Almost as interesting as the great emu war
