Tiny pebbles of cinnamon sugar.

The threat is desertification.

Many different devices have been used over the years to estimate the passage of time candles and sticks of incense that burn down at fairly predictable speeds have been used, along with the hourglass.

The first is to create a kind of balloon structure, fill it with bacteria, then allow the sand to wash over the balloon, pop the balloon, as it were, disseminating the bacteria into the sand and solidifying it.

So, we pushed the piles down through the dune, and we create an initial bacterial surface.

And, after an initial cost of 60 bucks to buy the bacteria, which you'll never have to pay again, one cubic meter of bacterial sand would be about 11 dollars.

Gold!

Very warm. And all that sand.

As rocks and mountains die, grains of sand are born.

It takes a pile of loose sand and it creates sandstone out of it.

You're beyond anal.

This is very small, and usually what you end up doing is taking a long stick and just kind of ramming it right up against the stopcock.

Sand

As I said earlier, it looked very much like Earth, so you see sand dunes.

Is there any sugar?

Would you like sugar and milk?

And as the sandstone weathers, new grains break free.

We have no sugar.

I don't like sand.

They're headed towards the desert.

And, sure enough, with all the other pressures on the river,

They're headed towards the desert.

This is not a desert. That is the desert.

Now the bacteria are dilute, that little hormone molecule is gone, so they're not making light but of course the squid doesn't care.

Now, you think about that now.

Desert

Sand

Sand Storm

And as it became cheaper, bread manufacturers decided to add in all kinds of things.

Sandlightning...

What is it?

Desert.

The Sahara is the largest desert in the world.

We have no sugar.

We don't have sugar.

We don't have any sugar.

There's no sugar.

This sun's really hot.

From there, we're actually going to get into what we call arterioles.

She splits the sandbag, the sand pours out.

Would you like some sugar?

How much sugar do you use?

And we thought that it could be a thermoregulatory behavior.

I'm fussy.

Ants are swarming around the sugar.
