Great post; I recently used honey for a normal incidence shear wave experiment. I tested my backyard honey vs. commercial honey and found my honey with a higher moisture content did not perform as well. Another thing: I switched from windshield washer fluid to RV water treatment for winterizing. It helps prevent the skin of the fingers from cracking.
I think the acoustic impedance of oil is pretty similar to water: acoustics.org/1pao9-the-acoustic-properties-of-crude-oil-scott-loranger/#:~:text=When%20an%20object%20has%20an,droplets%20could%20be%20acoustically%20invisible.
I think I can say I'm reasonably well-versed in technology and applied science, and I watched this entire video just to try to understand the purpose or the nature of what he's doing. I didn't understand. it has to have something to do with either sound equipment or something electromagnetic, but being measured by this weird scope that appears optical... what the heck is going on? ultrasound? what's the application anyway? this video has put me in despair. I'm beginning to think that this is some kind of mockmentary with this fuzzy and confusing technology, the kind of technology you would see in a dream, or a Rick and Morty episode. if so, this is next-level comedy. whatever this technology is, it appears to have almost like a cult following. that's why I think it is about hi-fi audio.
Being someone completely unfamiliar with the topic, I can very boldly state that I have no idea what any of what you just talked about means or what it could possibly even be.
Thanks 🙏 From Sarawak-Borneo
Thanks for doing these experiments for the greater good of UT.
Thanks Paul! Informative as always.
03:11 - awesome summary!
03:25 is hilarious hahahah - only after that did I notice how you say "aboot", ey?
Nice catch eh? I didn't notice that until you mentioned it!
inpedance water inpedance air, Excellent execirse to Understand the reflex ratio and transmission ratio. Thanks Paul for show this Pratical excersice.

yes, couplant is also important for inspection. the good couplant is expensive for daily usage.
Obrigado!
Thanks from Colombia #respect
Thanks for this great video. What about the oil? Does it also have nearly same acoustic impedance like conventional couplants?

Do you have any videos for UT thickness testing with A-Scope for corrosion monitoring. Training pdf can also help.
That's a good idea. I need to find myself a nice plate.

Such a waste of spicy sauce ;)
So, basically, No. 🤓
Yeah basically it's one of those rules that doesn't make any difference, usually, but we do it anyways because they tell us to.
