good idea, any thought on how it could be done? |
|
| |
Heh.
Google shows at least one. [link] |

...and just because it's new to me, so it might new to y'all, [link] 2 |

One way of making this:
coat the floor with a thin light-conducting surface. Pass light through the light conducting surface using total internal reflection (in a similar way to an optic fiber). When liquid falls on the floor, the total internal reflection is disrupted and light escapes the light conducting surface thus illuminating the liquid. |

concrete changes colour when it's wet. But apart from that, bone. |
|
| |
Actually, most materials change colour when wet, that is how we see that it is wet. A more pronounced effect would be nice, though. |
|
| |
Just incorporate some of those color-change-when-wet Barbie hair fibers in an epoxy resin so that they spell out the word WET when they're, y'know, wet. |
|
| |
Is there a suitable material that becomes transparent (or even semi-transparent) when wet, allowing an image or color to show through, yet is durable enough to serve as a top layer floor covering? |
|
| |
You could make the floor look like cartoon shiny blocks of ice. |

I think the problem is a matter of wear tolerance. The ability to function after buffing and waxing is also an issue. Reactivity is generally synonymous with perishability. On the other hand I could see a wash compound that went on colorful and dried translucent. I could also see some sort of optical function that would be affected by the presence of water on the surface acting as a prism. |

[mumble mumble mumble] redundant with the "Color-changing floor" xaviergisz dug up - although it's a different application (and one I'd admittedly much rather think about). Could you annotate the other idea with the new use for the same principle? |
|
| |
These are very different ideas. |
|
| |
I agree - the ideas are different (the other one advocates
rather dubious means to identify urine and distinguish it
from innocuous liquids, whereas this one seeks merely to
highlight nocuous liquids). |
|
| |
I read up to "So howzabout treating a floor with something that causes dramatic color change when wet?" The author then goes on for a bit, true, but at that point it's this idea, but without the warning sign. Meh, if it feels different to y'all, I'll be just as happy to keep it - let me know if you change your mind. |
|

look, neither one is really an idea, per say. |

//I could also see some sort of optical function that would be affected by the presence of water on the surface acting as a prism//
I was thinking of something along those lines too - a sort of prismic surface finish.
Maybe something like one of those lenticular images, and the water fills in the ridges, and suddenly an image becomes visible.
Not quite a colour change, though. |

[bigsleep] - You'd still need a sign to inform people that floor slipperiness increases the likelihood of falling over.
This isn't so good for the blind - the floor should have specially absorbent bits which swell up when wet forming little bumps which spell out "Slippery" in Braille. |
|
| |
...which you could then trip over. |
|
| |
How about a man who berates passers-by with a series of lubricatively appropriate anecdotes? |

If colour comes from tiny scale shape, just have water change the material's shape. Go even further and make a material that when wet, the shape makes the floor more grippy. No colour, no signs and no slips. Well, there has to be a colour change. |
