Seemingly trivial things that intrigue you

Why haven’t they come up with non-Newtonian fluid filled speed bumps?

Longevity issues?

Interesting concept but councils struggle to maintain tarmac, a load of custard filled rubber tubes is not going to help their maintenance regime.
Also, they would freeze in winter and some "war on the motorist" loon would probably stick a knife into them.
The current ones seem pretty effective anyway, hit them fast and lose a filling, slow down and feel a minor bump.

You’d think you could engineer something tolerable but I guess not for the cost of a sleeping policeman.

It's certainly an interesting concept, but think it would require too much maintenance in normal road situations.

Nice video, @pinno ... and can you remember what colour *the* dress was?

What problem does it solve?

If you drive slowly enough for it to remain fluid, you are going so slowly a traditional bump is not going to be an issue. If you are hitting it as a solid, it's still an unforgiving lump.

Blue.

Hang on...

Yay!

Aren't they meant to have gaps in them so that the emergency services aren't held up, like normal speed bumps? You can go over those a decent pace if you position the car right.

On a different colour... this is good.

That is weird, and not weird because it works. What is weird is that if I zoom into the yellow bottom right of the yellow segment only I still see a yellow edge. 🤔

If you squint really hard you can see a young girl and a clown.

Is the clown in the reflection? 😉

Because it is yellow. It's a yellowish white rather than a purpleish white,but there is definitely yellow there. Unless of course BR's image compression has added the yellow.

Agreed, but the text specifically states that there is no yellow hence my 🤔.

In theory the boundary around the "yellow" is created by the transition between blue and grey scale, I think. I can't zoom in enough to confirm whtmether or not the centre of each "white" line has a boundary or not. I am guessing not.

There is no yellow. This is the "yellow" section cropped.

Can you do that on a part with both blue and black? Am guessing that zoomed in, the "yellow" effect won't be visible.

Interesting. If I copy and crop the image it shows that there is no yellow. If I simply cover the other colours on screen it remains yellow. The brain obviously retains the illusion.

The blue circle looks like this



Pink like this



And the background looks like this (actually dark blue lines not black)



The "yellow" section is the only part of the image with actual black lines.

Not sure what processing you have done, or if the mobile site is compressing the images differently but when zoomed in the stripes are nowhere near that crisp or pixelated on my phone. Then there's the calibration of everyone's screen to consider.

First.Aspect

So the trick is that we think blue tinged "white" is what is actually white. Bit like how eyes adjust when wearing sunglasses I suppose.

Or when we think we see colour at night?

I copied the image and opened it in a photo editor. I could then crop slowly to see what effect it would have. Proved that the illusion works.

Just opened the image in a new tab and zoomed in. Took a screenshot and zoomed in slightly more.

I'm posting the same image just bigger, so any calibration your screen is doing, it should be doing to both.

rjsterry

I get the point of the illusion and what it's doing - it just doesn't look like what you have posted up when I zoom in. 🤷

Image compression here is a p1sstake. Anyway, the yellow area is made of white/grey/black stripes on my screen. The "empty" section is blue/grey/white.

A & B are the same colour
