In this lab, they use different flow visualization techniques to help detect contraband, residues, and develop trace particle detection methods. Part of this video was sponsored by Caseta by Lutron. Find out more at casetawireless.com/veritasium

Thanks to Rich Press and NIST for the great visit.
Thanks to Matt Staymates for taking us around his lab and showing us the fascinating research being done with flow visualization.
You can check out all the cool work going on at NIST here: www.nist.gov/

This is the first time I've seen Derek is completely quiet almost throughout the entire video and not having to ask many questions or prompt the speaker and explain it to the viewers because Oh My God! The way Matt explains this is almost like listening to a cinematic story teller taking you though some of the most mind blowing scenarios and you are actually visualizing in your head the vivid details he's explaining! He's like the OG CSI!

Matt was 100% right about most people not sitting down and read a scientific journal. Your channel is proof enough for most (I feel like). I know I have never been like "Hmm. How do I measure the tiniest forces in the universe?"... but I still watched your entire video. And like he said, the problem isn't the science itself, it the communication. Being able to actually SEE the effects/proof of what is being talked about is a much easier way for media to convey their information.

This guy should have their own YouTube channel. I could listen to him talking about stuff for hours.

These NIST videos have been fascinating. There’s nothing better than hearing straight from the experts who also happen to be engaging and interesting people!

You with Kurzgesagt are in my opinion the overall best scientific educationnal channels ever, and I feel so priviliged to be able to watch those videos for free.

The laser sheet method definitely makes me think of the moment a sun light beam enters my room and I first see small dust particles floating in that beam.

I have the attention span of a chihuahua and was focused the whole video. Awesome work!!

With the laser sheet, I wonder if using several different laser sheets of different wavelengths stacked closely together, you could analyze the color of it to model the flow of the air over the table in 3 dimensions.

This was the area of my research ~10 years ago. I was very pleased to see how this was presented and explained in this video. Well done!

This video is amazing. It's not only very specially informative, but the enthusiasm behind science is incredibly infectious. So, thank you to you both. Rich, you are a great educator as well as you Derek.

This was easily one of the most interesting videos I’ve seen in about 15 years of watching YouTube. This struck directly at the types of things I think about all the time - micro fluid dynamics - super super interesting. Thanks! Lucky enough to have visited the NIST lab in DC (for energy related topics)
