But what it led to was we showed fluids could do...

It'd been known fluid could do logic, like your old automobile transmissions do logic, but that's macroscopic.

It didn't work at little scales.

We showed with these bubbles, we could do it at little scales.

Then I'm going to come back and explain it.

But what came out of that is Manu then showed you could make a 50 cent microscope using little bubbles.

And then the techniques we developed are what we use to

transplant genomes to make synthetic life all came out of the failure of trying to make the genome, the ribosome.

Now, so the way the bubble logic works is in a little channel, fluid at small scales is fairly viscous.

It's sort of like pushing jello, think of it as.

If a bubble gets stuck, the fluid has to detour around it.

So now imagine a channel that has two wells and one bubble.

If the bubble is in one well, the fluid has to go in the other channel.

If the fluid is in the other well, it has to go in the first channel.

So the position of the bubble can switch.

It's a switch.

It can switch the fluid between two channels.

So now we have one element of switch.

And it's also a memory because you can detect whether or not a bubble is stored there.

Then if two bubbles meet, if you have two channels crossing,
