Otters React to Anti-Gravity Water Drop Illusion

[@Sasser2015]

I worry that if Kotaro drinks too much anti-gravity water, we could see our first ever flying otter and ultimately, space otter. He's really smart, so please at least show him Japan on a map so he can get home if he winds up in orbit.

[@cherylhulting1301]

[@TheMightyX]

Watching Kotaro lick the water stream is probably the cutest thing I’ll see for a very long time.

[@TheRyujinLP]

It's quite remarkable how intelligent they are. The fact that he was amazed by the water flowing up means they understand a sense of natural order and can appropriate that there must be some mechanic that is making the water act against its nature and he even goes so far as to to try and rock it and knock it over to see how this would affect things. Equally it's also remarkable how heckin' adorable these guy are. Though I would imagine these are not easy pets to have and has taken a lot of work and love to get these lil guts to this point.

[@alkimia1791]

I didn't even think about it like that! That honestly makes me love them even more though!

[@ktgame2640]

Hahahahaha...Surely the otter wrote it down in his notes.

[@TheRyujinLP]

@nerdiest of nerds! Nope, it's the gimmick of the product. I've seen one IRL before and that's how it looks. I does use the same basic idea behind the trick using a strobe light.

[@TheRyujinLP]

@nerdiest of nerds! No problem man. I'd probably of thought the same if I didn't see this in real life first.

[@VinnySlouth]

According to QI birds see at a different rate to humans, so watching a movie for a bird would be flickering images. I have to wonder if otters eyes are closer to humans or birds, mammal might be a clue but I wonder if they are seeing the same thing we are seeing?

[@SamwellBritton]

This is incredible I had no idea that Otters display this amount of intelligent curiosity and understanding, communication.....and so dextrous. I used to equate them to cats in intelligence but just this example shows so much more, higher thinking. The Otter understands that the water can't be coming from nowhere and checks under and around the base for the connection. It's a very abstract leap to make.

[@Eagle_Owl2]

No wonder! Mustelids overall are a pretty curious bunch. For example, ferrets rank above cats, dogs and several small primate species when it comes to their problem solving skill. Weasels, mink, polecats (including ferrets) and otters display similar behaviour when faced with challenges or new situations. So they all probably have pretty neat problem solving skills that are aided by their immense curiosity.

[@s-c..]

I had no idea they were so adorable, or that people keep them as pets, but they look like a lot of work to keep entertained! Were those the noises they make?

[@goatyqt4553]

@@Eagle_Owl2 Not an expert at all, but this might come from their general ability to move in tight spaces. Evaluating where you’re gonna go is crucial if you want to not get buried/stuck. Just my theory though.

[@Eagle_Owl2]

@@s-c.. honestly, otters are awesome but they make terrible pets. Some otter species are also threatened by increasing animal trafficking because they become more popular as pets because they're so cute. But what you see in the Hana and Kotaro videos are exceptions. Most otters aren't kept well and many otters that have to live as pets become aggressive because their needs aren't met. And trust me, you don't want an aggressive otter. I had ferrets for nearly a decade and I worked in a wild animal sanctuary and mustelids have the nastiest bites. If you're interested in mustelids as pets, look for ferrets. They are at least domesticated since 2000-4000 years and very friendly if kept well. But even they are more complicated and especially very expensive pets (diet and vet).

[@Eagle_Owl2]

@@goatyqt4553 could be a factor. They are also relentlessly stubborn, so they only turn away from a problem once it's solved. My ferrets sometimes tried for hours or days to reach a place they shouldn't access. That's why ferret-proofing a home is pretty difficult (I'm absolutely against caging ferrets). They are great family members though. Intelligent, social and cute. Though most other mustelids are not very social :D But they're all intelligent and cute.

[@cherylhulting1301]

I'm not sure why people are missing the fact that Hana was trying to examine the properties of this device herself. And as pointed out earlier, she got sprayed when Kotaro was playing with the shower hose and immediately left the tub. Her hatred of the hose may simply be that she does not like getting sprayed by water jets. You can see this if you pay attention to her behaviors.
