Toothpaste is a perfect example of the Pareto principle: the last 20% lasts 80% of the time it’s used.

    My toothpaste tube can hold an infinite amount of toothpaste. No matter what, I can always get another brushing’s amount out of it.

    My dishwasher also can hold an infinite amount of dishes. No matter how full I think it is, I can always fit another item with just a little rearranging.

    I don’t think you’re using your toothpaste correctly.

    I think what’s happening is you start by squeezing from the middle and it soon begins to look like the toothpaste is depleting quickly, only for the rate to slow and the tube seemingly lasts much longer than initially anticipated.

    A couple of things are happening. One is that the toothpaste, due to pressure being applied unevenly across the surface area of the tube, is gathering in parts of the tube that can store more volume than their appearance lets on. I think this is due to the odd shape of most tubes which is a cylinder that tapers down into a two point line. There is always a lot more toothpaste left in the head of the tube than you think!

    The other factor is that, at least for myself, I start becoming conscious that the tube is running low and so I start using a bit less each time I brush. That combined with there being more left in the tube than it appears could mean you think you’re down to 20% but you’re really still at 45% and you start using less so it takes 50% longer to use up the remainder.

    Oddly enough that’s how my gas tank works as well

    When I have a full tube of toothpaste i myself am full of hubris. I put a huge glob of toothpaste on my tooth brush every time I brush. I believe the store to be unlimited.

    As the tube becomes more and more empty, I put the little dollop on recommended by the instructions.

    Huh? How do you figure that? Are you putting massive gobs on your toothbrush till you have to work to squeeze it out?

    I feel like finishing toothpaste, like chapstick, is a memory that will simply never exist in my mind even if it’s happened

    My wife always tries to tell me to throw away a tube and then I use it for another 2 weeks.

    Listerine is mostly backwash by the time I breakdown and get another one, too.

    I am terrible at fishing out those "last bits" in a lot of things. Peanut Butter gets tossed often with a spoonful left that my big-ass hands can’t manage to get. Remnants of drinks get tossed. Etc..

     

    I will get every last damned molecule of toothpaste out, however. Or I will die trying.

    Infinite toothpaste glitch i just use half of the amount remaining every brush

    You’re using way too much.

  22. Opnes123 Avatar

    That does make sense. When our toothpaste is new, we put in on our toothbrush generously since it feels never ending. But once the tube gets to less than half, we try to skimp on it to make it last even longer, especially if we haven’t bought a new one yet. Strange but true!

    I’m not well off by any means, but I fucking refuse to fight my toothpaste or my deodorant to get that last bit. Plenty of areas where I cut costs and reduce waste, but once that toothpaste tube requires anything more than a gentle scraping to the top, I throw it out. Similarly, if I can start to see the lines where the bottom of the deodorant stick is mounted; garbage. I got so fed up with sandpapering my armpits or struggling to get the toothpaste out of the tube

    I feel like I use just a tiny bit every time, but the tube is always packed with so much more that goes to waste. Maybe we need a ‘toothpaste squeeze’ system to get that last 20% out more efficiently

    Never thought of it before but seems true when I look back. I’ll use it differently once it has gone low especially if I don’t want to go shopping any time soon

    Interesting observation! It really does seem like that last bit of toothpaste stretches out forever.
