Non-Newtonian gel experiment.
Added 2019-11-04 17:07:51 +0000 UTCHaving seen the use of a non Newtonian gel as an impact absorber I decided to make some and then hit my hand with a hammer to test it.

It appears to work.
This is also a fast and fun project to make "slime", which has a very tactile feel when handled.
I recommend getting some Borax (not the substitute) from eBay or your local hardware store. It's one of my recommended stock chemicals.

Apparently Blu-tak fall into the non-newtinian fluid family.... known about these for years but would never have applied it to Blu-tak.

2019-12-16 17:43:24 +0000 UTCI thought "Mk 1" would be the first version of something? or did I miss the joke maybe? :-)

2019-11-07 21:17:36 +0000 UTCI think I mentioned this previously but I run an actual X-Ray at work and had to re-name my hammer "X-Ray MK1"

2019-11-05 07:08:07 +0000 UTCIt's the technical slime video. No glitter involved, although I did add some gold mica powder to a batch and inadvertently made the WORST glitter slime ever. It looks beige, but when you handle it your hands end up covered in fine glitter.

2019-11-05 07:07:49 +0000 UTCDidn't realise my first slime-making video would be this one, but I think it was the right one :)
2019-11-05 06:50:25 +0000 UTCWas that borax (20 mule team borax)? Is this stuff similar to the corn starch mixture that makes funny shapes when suspended above a big speaker with the waveform generators? Maybe stick an oscillator in a little chunk of this stuff?

2019-11-05 02:29:24 +0000 UTCPVA(alcohol) is prepared by hydrolysis of polyvinylacetate. as wiki page states. just looked it up.
2019-11-05 01:07:35 +0000 UTCMight be nitpicking, but during my education as a jointer(furniture carpenter), we learned that (the wood glue) PVA is Polyvinyl acetate. :) If the other is Polivinyl Alcohol, that might be the difference as why acetate doesn't work.
2019-11-05 01:05:07 +0000 UTCBorax is dangerous, in microwaves it makes the magtrometer explode, it should be outlawed. If you don't believe me, believe industry expert Sarah Faye Pierce.

2019-11-05 00:21:47 +0000 UTCFun video. I think the commercial PVA glue cross links as it dries when gluing surfaces together. I have also bought borax made up to kill wet rot.

2019-11-04 20:28:04 +0000 UTC10 million subscribers suggest he has a good market for his content. People who want to see him enthusing about stuff. You can always tell when he actually thinks it's crap though.

Big Clive
2019-11-04 20:26:28 +0000 UTCIt does pick up dirt from crevices, but a more elastic version might be better to avoid filling the crevices with loose slime.

2019-11-04 20:25:42 +0000 UTCSlime videos are HUGE on YouTube. Thinking of pivoting? :-)

2019-11-04 17:33:01 +0000 UTCI have seen a type of slime, used to clean things like auto arm rests, and irregular surfaces. Is this the same ?
2019-11-04 17:32:18 +0000 UTCInteresting in regards to the Borax. Big Pharma at it again.
