  • Yes. It’s not necessarily the size that makes the noise, but rather the rpm required of the smaller fans to move an equivalent amount of air. I have a fan in my phone, for instance. It is so small that it spins at 23,000 rpm to make just a small amount of air movement I can barely feel, but easily hear. My ceiling fan can’t be heard at all but still moves WAY more air while spinning at a couple hundred rpm. The air turbulence from blade speed is most of what you hear from a fan.


  • It’s just some standard fluid dynamics. It uses “Bernoulli’s Principle” and the “Coanda Effect”.

    You can look up those, or probably look up those along with “dyson bladeless fan” to find a more direct explanation. The gist of it is that the ring of moving air causes a pressure drop inside and behind the opening that causes the air from further behind the ring to rush into the low pressure area and get pulled along through it.

    It’s also just Dyson’s completely overpriced bullshit. It makes weak air flow and has no real benefit for use as a fan.

    Project Farm has tested them a couple different times. They’re expensive aesthetic toys.

    *Edit: While I’m on a bit of a Dyson rant; I’d just like to also say that I HATE their hand dryers that some places bathrooms use.




  • I was there by 5th grade and read grade 5 in first grade. I never read a ton, but I gave cred to my grandma, who would read me “the pokey little puppy” when I was 2 and 3 and 4 years old like every night I was there (a lot).

    I had the book memorized and was able to follow along to all the words without knowing how to actually read or anything about sounds. Apparently that was a big leg up in learning to read.



  • There’s still plenty of velocity to kill and it still hits harder than a .22 out of a rifle.

    They aren’t even super terrible to to shoot as far as kick back and such, but I’d still call them pieces of shit. The rounds will sometimes tumble through the air, they’re inaccurate, and since they only hold one round, they’re kind of useless for something other than having around as a curiosity.

    I’ve seen a few different models of these pocket sized single shot rifle round lobbers. They work. They’re deadly. They’re just kind of dumb.









  • It’s not your fault. The taco bell one really tucked me off, though. The first summer it was out was a limited time thing. It was actually a bit spicy. A lot more spicy than anything else a fast food chain had.

    But then when they brought it back permanently it wasn’t half as spicy as it was. Taco Bell has like 5 fucking bland ass sauces now, and three of them taste about the same. What’s the damned point? FU taco bell. You could have left me with at least one option besides all your ketchup with tobacco sauce mixed in. No wonder I’ve only been there like 4 times in the last year.
