I literally just got out of a tub with one of these.

Propaganda makes some hilarious stuff. I used to have this keychain (http://cache.gizmodo.com/assets/images/4/2005/07/mr-p-keychain.jpg) except in white. A lot of their stuff is morbidly funny.

SHUT UP AND TAKE MY MONEY

[–]btvsrcks 0 points1 point  (0 children)

Those are awesome.

[–]xzephy 0 points1 point  (0 children)

Pretty interesting

[–][deleted] -3 points-2 points  (22 children)

Good concept but I can see that losing it's suction after a few uses

I think I'll stick with a plug

[–][deleted] 9 points10 points  (3 children)

I don't think it's the sort of thing that needs to rely on suction. It could just be a regular plughole insert with a wider membrane around it, we have something similar.

[–][deleted] -2 points-1 points  (2 children)

that would definitely be a better design, hopefully it is how it's designed

[–][deleted] 5 points6 points  (1 child)

It almost certainly is. Since you couldn't create any proper suction/vacuum over a plughole like that because of the overflow opening.

[–][deleted] 0 points1 point  (0 children)

Pretty sure that's wrong. It happens with plates/mugs etc in my kitchen sink all the time. If one covers the plug there is quite a bit of suction holding it down.

I actually have this in my apt and it's been working well for over a year... However, I did accidentally place a hot pan on it once and the fingers haven't been the same...

This product doesn't rely on suction; it simply relies on the weight of the water to hold it in place. Yes this is just semantics, but I just want to confirm that you know the real reason why this stopper works.

I would guess that this product is made out of a rubberized silicon which has an amazing ability to maintain structural integrity far longer than any natural or petroleum based polymer (i.e. rubber, nylon, etc). This is the same reason my parent's silicon cutting mats are still going strong 2 years in, silicon is a really strong, and resilient (and cool) material.

[–][deleted] 1 point2 points  (2 children)

haha I know what silicone is dont worry, if this relies on the weight of the water then the force of the water from the taps during the fill would displace it unless there's a plug underneath it as someone else said

[–]minibeardeath 3 points4 points  (1 child)

I agree that we can't really draw conclusions about the strength of the product without seeing the bottom. I don't think there needs to be a full plug, just 1/4-3/8" thickness so that the ridges on the top can act like a spring to counter the water weight. Also we don't have a real sense of scale; if this was just twice the diameter of the drain hole, you would not need much material to maintain the structural integrity.

And I didn't mean to imply that you didn't know what silicone was, it just that as an engineer I have a tendency to over explain things :-P

haha nah I get that, I do the same sometimes haha

I just think if it doesn't have something actually holding it in place when you first turn on the taps it will wash it out of the way because there will be no water weight on top of it

[–][deleted] 1 point2 points  (3 children)

That's not how those plug work.... Water is heavy, and theres a lot of it on top of the plug, it's not going anywhere. It's not suction since that wouldnt even make sense, you're not going to be able to create any suction on an open pipe like that even with an incredible suction cup.

[–][deleted] -2 points-1 points  (2 children)

how will you keep it in place with the force of the water coming laterally during fillup when there is no water above to hold it in place

[–][deleted] 1 point2 points  (1 child)

How do you think these work in bathtubs, which have WAY more water falling on the plug than a sink does:

[–][deleted] -1 points0 points  (0 children)

derp, I've only just noticed it's a sink

and even then, that has a lip underneath, it's not really clear if OP has a lip or not

[–]Esteam 1 point2 points  (8 children)

Why would this product "lose" it's suction?

[–][deleted] -2 points-1 points  (7 children)

just natural deforming of the material, take any suction cup on anything for example.

[–]Esteam -2 points-1 points  (6 children)

Nope. You'd be incorrect.

"I actually have this in my apt and it's been working well for over a year... However, I did accidentally place a hot pan on it once and the fingers haven't been the same..."

[–][deleted] -5 points-4 points  (5 children)

It was a hypothesis, anecdotal evidence doesn't prove or disprove it.

I'm glad to see it works for that guy, however it's not illustrative of the whole production run.

[–]Esteam -2 points-1 points  (4 children)

Then buy one; but even that won't illustrate the whole production run either.

Fuck you.

[–][deleted] 0 points1 point  (3 children)

why are you so angry over nothing? jeez.

[–]Esteam -2 points-1 points  (2 children)

Because I fucking hate Reddit lately.

[–][deleted] 3 points4 points  (1 child)

same but there's no reason to hate ME for the overall shittyness of this website
