Why Snatch Blocks are AWESOME (How Pulleys Work)
I love Smarter Every Day, but I worry that if someone ever figures out how to combine laminar flow and snatch blocks that Destin's brain might literally explode.
Baseball Pitches Explained, in Slow Motion
Great stuff. You never once mention laminar/turbulent flow. Are none of these pitches affected by rough/smooth surface of the ball?
Pouring water down a 50 meter well
It accelerates at up to 9.8m/s^2 (- wind resistance)but terminal velocity can be well below or above 9.8m/s, depending on how (or if) it breaks up.
(I could only find terminal velocity data for droplets up to 3mm, and studies did show droplet stability up to 6mm outside laminar flows)

....so...sorcery.
Arrggg, the water is falling at 9.8m/s^2!
WTF is this witchcraft???
An awesome fountain in Chicago
Cool. That's not the kind of laminar flow I was expecting. It's like an artistic version of this.....

This engine sounds so sexy
Looks like they got a lot of work to do, that plume did not look too laminar.
Water Droplets on a Superhydrophobic Surface
>> ^mizila:
>> ^jimnms:
If they coated boat hulls with this stuff, would they cut through the water more efficiently?
No, that's how you make hovercrafts. :-P
But seriously, smooth hulls are actually bad for speed. Ideally you want little pockets of air to make a good boundary for the laminar flow of water going past. Some people even sand the hulls of their racing boats. Think about the dimples on a golf ball, same idea. Although it'd be an awesome product for the windshield of a boat. =)
Yep good point, and if you look at/touch shark skin, it's essentially sand paper; helps them move faster through water apparently.

Wow, cool virtual Laminar Flow.

Someone unswirled her video. Now she's just a mental, laughing weirdo: http://www.youtube.com/watch?v=T0PAgrm8nqg
Twist in Time - Laminar Flow
No problem, different enough vid.

Oops, sorry everyone didn't realise there was another laminar flow video, it didn't show up on the related videos when I posted it.

thats because your tags did not include the words Laminar, the other persons does, if you did, then magic wou ld of happend and siftbot could of done its job.
ALTHOUGH, the videos are not dupes, I was just showing that there is one on here, your seems to have an actual explanation.

I will wager a million bucks that I've seen this here before... *goes off to search*
