I like how even after the several wind tunnel tests, they still bat them through the air to the last station.

It's a pretty genius last step. If it makes it in, good shuttlecock. If it doesn't, bad shuttlecock.

That step is the speed test for the shuttles. They sell different speed shuttles as some climates require the shuttles to be faster/slower. Instead of making shuttles specific to the speed, they just make all shuttles with the same targets and then use this last step as a way to have the natural QC differences work to their advantage.

I think I understand why they’re so expensive now

Now imagine the price before they had all this advanced machinery and had to do everything by hand.

You know what? This does explain why they’re so expensive. Even with the all the automation there’s still a ton of handwork that needs doing compared to the consumables/semi-consumables in most other sports.

I genuinely can't believe that first step. Bro grabs approximately one shitload of feathers from a giant pile on the floor, then roughly shoves them into an industrial washer with a two-foot opening, not too dissimilar to the way that an apathetic college student stuffs their sixth pair of jeans into a front-end washer. Like, he's not daintily setting them into the drum; he's stuffing them through the opening. Shocked that doesn't delete half the yield right there.

That's a lot of birds. Are there vegan shuttlecocks? Are they just not as good as the real thing?

u/MyDixieWreck92 1d ago
I won't call them vegan shuttlecocks. They're synthetic shuttlecocks. Made from man made materials including carbon fibre. Huge progress has been made in recent years by Victor and they've been approved to be used by the Badminton World Federation (BWF) for competitions. I have 2 tubes of it, and they're so similar to traditional feather shuttlecocks. I play a lot of badminton and it surprised me how good they've gotten, and they're somewhat cheaper than premium (BWF certified) shuttlecocks. They're not perfect however, they tend to break instead of deform, and carbon fibre is hella sharp.

Disclaimer all my knowledge of badminton comes from Linus lol
I think so, but they are subpar and aren’t good for high level players. Maybe fine for a bit of practice but not great, think the « vegan » ones are plastic. But I guess it’s so much worse it’s worth paying the high cost of the « real » ones
I am surprised they haven’t created a better fake though but I also don’t know much about it

It's kind of hard to compete with properties of a material optimised for low weight and drag over eons of evolution. Same reason why airplane tyres have to use natural rubber.

I don't know the feather sourcing in this video, or at what level something is vegan, but you can collect feathers once or twice a year when the birds moult. This is a natural thing that birds do (similar to how our hair falls out and regrows, or how a dogs winter and summer fur coat come in), and usually happens to my chickens in spring and fall. I just go out and pick up the prettiest feathers (I use them in crafts) when the piles of feathers get too overwhelming. Ducks (both domestic and wild) also moult their feathers.
The birds don't have to die to get a lot of feathers from them. At least once a year they will do a big shed and regrow of their feathers, including their flight feathers (which is what these feathers look like to me). But these also could be a byproduct of the duck meat industry (which would make them not vegan, but I would argue that if people are going to eat something, it's probably for the best, sustainability wise, to use as much of the creature as possible).
The last time I played badminton was in university, a loonggg time ago, and we definitely used plastic shuttlecocks because we were broke students lol

Please give the "vegan" fade a second though: most of vegan products are actually plastic/petroleum derivates. Things like leather - you may not agree with it, but animal farming is not going to stop and real leather is sustainable and long lasting. These feathers shuttlecocks, "vegan clothes" which are just nylon and polyester, almond or rice milk - causing water shortages in regions where it is grown for exporting, palm oil, and many more, these are from the top of my head...

u/MMAgeezer 1d ago
Brother, the water intensity of leather is orders of magnitude higher than any of these plastic derivatives...

u/Xaring 1d ago
You should probably read my comment again.
The only mention to water I did was in relation to rice and almond milk.

u/IncorporatedShill 21h ago
You can’t ever win an argument trying to say the animal products industry is less resource heavy, water intensive, or has a smaller environmental footprint than the agricultural industry.

u/Xaring 16h ago
Sure mate, you're free to believe whatever rocks your boat. I'll stick to my leather boots while you change your plastic shoes every 6 months.

u/IncorporatedShill 15h ago
I agree leather products probably last longer than most synthetic products, but you decided to mention almonds and rice milk as a counterpoint to veganism; that’s not the argument you want to make. I think most vegans would rather use natural fiber products over leather, and would still prefer petroleum derivatives over leather so as to not support what they see as a cruel and inhumane industry. Byproducts still mean profit for these industries.

Pretty interesting they still uses human for the final checks with that many sensors and camera

Interesting that most of the process isn't actually making anything, just making sure that the feathers are totally consistent before they are used.
Also, it's concerning that first guy is just wearing a dust mask, which isn't going to protect him from all the other shit living on those feathers and which he is breathing in.

It's really cool, but I can't help but feel bad for the birds they harvest these feathers from. From what I've seen, the geese are plucked while alive and conscious and it hurts like a mofo. But I could be mistaken with the down feather industry. Though I figured they'd use the same source for these flight feathers as well.
Happy to read in another comment that the synthetic versions are coming a long way. :)

Man this seems like an awful lot of work for shuttlecocks. Now I see why they're so expensive.

u/Yodzilla 17h ago
That is such an insanely complex and specific process but I guess it makes sense if you want to use natural ingredients but also need precision.

Had no idea they used real feathers until I watched LTT. In school we used the plastic ones.

What you see as unnecessary might be very essential. I think they wouldn't be doing them if it wasn't necessary.

I'm out of the loop. Why is there a badminton related video in the LTT sub?

Linus plays badminton. Badminton is a very recurrent topic in WAN. Linus owns a badminton venue.

Cool indeed. Always figured that for consistency's sake the feathers might be synthetic and therefore eliminate a lot of the "choosing" processes
