Some time ago in lecture hall E, a quite honourable gentleman tried his hardest to slapp'nfold wet flour into a firm dough. Its a relief to see that since then lecture hall E turned into a clean and useable space again.
Great video. As a fly fishing guide, nylon is near and dear to my heart… my challenge right now is to change its properties to make it more elastic without memory… I’ve achieved 25% stretch with just boiling water and salt, but the coils are still there and the nylon monofilament retains memory when it cools… any thoughts on how to chemically and permanently remove memory from nylon while preserving knot strength?
Have you made any progress in this pursuit? Would you be willing to share (via email?) What you've found about nylon thus far? I am researching it for product development.
Because it is a condensation reaction, where the by-product is water (which interferes with the reaction), the polymerization as shown in the video doesn't make a very long chain polymer. Wallace Carothers figured out that distilling off the water as the reaction happens makes a longer thus stronger polymer.
flixborough disaster brought me here... please may I ask what the chemical equation is? The one I have is: C6H12 + O2 -> (CH2)5 CO + H20 ... But this only accounts for the cyclohexanone not the cyclohexanol... so I'm not sure it's correct
How can we disassemble those polymeric chains in old nylon and polyester to make a new product? We make American flags with nylon and polyester. Currently the proper way of retiring American flags is by burning it which is ridiculous. We are looking for a better way. 90 million pounds of nylon flags are retired each year.

We actually filmed in Hall B, not sure why Daniel called it "Hall E"?
@@NatSciDemos so the man is still slappin'......?
@@paulbin Still slappin'. Science and Cooking will be meeting this fall.
O Jesus you are wonderful....... such a wonderful experiment....💫👍👀
Awesome video!
Thanks!
2:27 this remind me abt junior high, when i tried to pull a string out of correction fluid. Very satisfying!
Cool stuff

I don't understand what would've been so difficult about washing the final product and remelting for application in commercially viable stuff?

@@DanielRosenberg ah I c, neat
amazing!!!!!
Is this the same for classical guitar strings? Greetz from 🇨🇭
That's what i get excited for
Sahi hai 👍🙏🙏

How much is this strong?
If it's strength r good it's can be use as homemade home use...

Wow🇧🇩❤

The question is: Why are you using mask?

One dislike me
Why are you warning that mast. ? You lost me amateur.
This is what I make all day at invista canada
