This is what happens when my little girl gets a hold of the iPad. She takes a bunch of selfies that get backed up to Google+ and auto-awesomed.

Circle area by rearrangement

A very intuitive visualisation!

A disk is divided into sixteen pie pieces and unrolled along the circumference. The resulting row of spikes is then split in two, one half is rotated and placed interlocking with the other half. Below, another disk is unrolled into a continuous gradient, simulating infinitesimal spikes. It is similarly split, rotated, and merged with the other half.

This is why I emphasize TWODA - Things We Ought to be Doing Anyway. It's fine to ask questions - yes, skeptical ones(!) - about climate change consensus.  But only a fool would refuse to do basic, prudent and sensible precautionary measures, just in case scientists and experts turn out to be right.   

And no, the agenda of (nearly all ) science-friendly folk is NOT to "ruin the economy" or to "shiver and starve in the dark."  TWODA is about investing prudently in energy efficiency -- and after 25 years of delay, the new car mileage standards are working brilliantly.  Efficiency that would save us all money, create energy independence and have scores of other benefits...

...hence the acronym TWODA... Things We Ought to be Doing Anyway... even if climate change were completely wrong!

It is the utter refusal to negotiate even mild versions of TWODA that belies every denialist claim of reasonableness, and exposes it as a raving, anti-science cult.

At the very least, we should end subsidies for fossil fuels.

It turns out that those welfare states, with their generous social benefits, are beating America at job creation hands down.

The good news is a vigorous plan of action should hold it down to only half a nice age unit.

Probably you would get a cloudy grey mess. The polar liquids (water, alcohol, corn syrup, etc) will mutually dissolve, as will - I think - the non polar oils. The soap will then allow all of it to mix. It's surprisingly stable if you don't agitate it too much though.
