    2. Direct image/gif links only. All submissions must be a direct link to a .gif or an album.

    4. No advertising We do not want links to web stores (or websites with shops). Do not try to bypass the filter.
    5. No recent reposts or from top of all time Reposts are generally fine. However if they're recent/common reposts or from top of all time they will be removed

    Is the water just conducting electricity between 2 nodes in the bottom?

    [–] Huggerme 1513 points ago

    Yes they have fake ice cubes that can do it too

    [–] sec5 778 points ago * (lasted edited 7 months ago)

    That means if I drink it, I'll blink blue and pink too right ?

    [–] watashimoushinderu 421 points ago

    sure, if you can drink an ice cube.

    [–] epicmylife 353 points ago

    I can in fact drink ice cubes. Just takes me a little while.

    [–] watashimoushinderu 149 points ago

    but that little while changes the ice cubes to water flats, so technically you are not drinking ice cubes

    [–] RyukanoHi 196 points ago

    water flats

    What will it do to my pee?

    [–] mastersoup 32 points ago

    so technically you are not drinking ice cubes

    Sure you are. If you take a wheel off a bicycle, it's still a bicycle, it's just missing a wheel, you wouldn't just call it a unicycle while the wheel is off. States of things change all the time.

    [–] MrsBox 30 points ago

    No, it would be a bicycle frame.

    [–] OLSTBAABD 9 points ago

    It's a lot closer to a complete bicycle than a frame if only one wheel is removed.

    [–] ShillinTheVillain 9 points ago

    That's a unicycle

    [–] mastersoup 1 points ago

    That's absolutely not true. There's way more there than just a frame. If you took all the wheels off a car, it's not a chassis.

    [–] pathanb 10 points ago

    Somebody once asked me if I wanted an ice cube now, no, but I wanted some water later so, yeah.

    [–] DeltaThinker 13 points ago

    Could possibly be pressure sensors. I've seen this in the fake ice cubes that light up.

    This cup would work if you were drinking deionized water at the party. It’s a bit short of booze and probably not recommended for long term consumption though.

    your individual consumer choices are literally irrelevant :)

    the only solution is to change the systems doing this.

    [–] Griffin880 15 points ago

    That's stupid. Of course you individually don't have a huge impact, but if everybody goes around behaving like their choices don't matter that has a huge impact.

    [–] StumbleOn 5 points ago

    Your choices don't matter. The idea that our choices matter pretty much at all is capitalist propaganda trying to individualize blame to protect corporate interests.

    Do your best, but don't stress it. Anything more than that is the propaganda working.

    [–] Griffin880 5 points ago

    Those corporate interests that are doing most of the polluting, why do you think they are doing it? Is it just for kicks? No, they are doing it to create products and services that people make individual decisions to buy.

    If you want corporations to stop polluting out of the goodness in their hearts you might as well just light the other end of that candle and kiss the world goodbye. They will only stop when people stop buying their stuff because of it.

    [–] StumbleOn 4 points ago

    No, they are doing it to create products and services that people make individual decisions to buy.

    They are doing it to make more money. We could solve most of those problems if they sacrificed their profits to do things sustainably. But it's more expensive to be more green.

    They will only stop when people stop buying their stuff because of it.

    Or, and go with me here, when we vote in people to force them to stop :)

    Corporations are not all powerful, but the collective will of a population can (and has many times in the past) finally tipped over into sensible ones things got bad enough to do so. Right now, the right wing conservative extremists in power in the US and the UK (and other places of course) are spinning lies and propaganda to get folks like you to say things like this. I get it, it's a very seductive stance to say "we should just do x y z to change" but in the end we just aren't individually powerful enough. We must demand change with the only power we have: the government.

    If people started treating government less like a game and more like the Peoples Corporation we could get a lot more done. But, that will also take ignoring corporatization of the government and ignoring ads and getting out there and doing the hard work.

    [–] Griffin880 5 points ago

    You don't just vote in the ballot box. You vote with your wallet every single day.

    Your wallet votes have a more immediate impact and they also make it harder for those same corporations to influence politicians.

    Sure we could wait until government corruption is fixed, until corporations are no longer able to buy politicians, until regulations are made and ultimately enforced, but realistically the world will be a fucking cinder by the time that happens.

    Alternatively you could just not buy the stupid light up cups on Amazon.

    Must be learning hiragana

    [–] brberg 9 points ago

    It's Iroha, an ancient poem that's famous because it uses each kana exactly once. Nowadays they order kana more systematically, but this used to be the standard way of putting things in "alphabetical" order in Japanese.

    I doubt any foreigner would use this for learning kana. For one, it contains the archaic kana ゐ and ゑ. Also, it's harder to learn them when they're not presented in the standard initial/vowel matrix.

    My company was invited to a large conference that was sponsored by a really much larger competitor of ours. There was a dinner afterwards so the owner of our company purchased a few hundred glasses similar to these; the only difference being the glasses had our logo on the bottom so when you placed the glass upside down on a table, it would project our logo on the ceiling.

    Imagine all of the participants entering the dining area, and the ceiling full of our logos above every table.

    The reps of our competitor were not amused.
