It is our first broadcasting, so do not tease him.

And I also bring an innovation here.

They scribe along a place there.

Please click on the marked laser to shoot a beam into the black box.

The old man crooked his finger as though he were firing a gun, and then he made laser sounds.

(Music)

Lasers

Laser

very crazy and very, very hard to find.

Laser

'Laser Man' ...

Lasers

Lasers. Check.

Birds on stage, back projection, laser beams!

Activate automatic repulser guns.

Just use your lasers until I give the signal. Remember to lead...

OK clankers, SUCK LASER!

Find the balls hidden in the black box by shooting laser beams!

It also uses photons, but they're all synchronized, and if you focus them into a beam, what you have is an incredibly useful tool.

Laser power draining!

Target is lased.

Now to do that, first we need to trick brain cells to respond to laser beams.

Next we can actually light them up with a laser. (Laughter)

R2, intercept the lasers

Yeah, there's guns and glow lights, and kids wear the vests...

(Laughter)

Now,

Weapons on! We have them now! Fire.

We can destroy the laser emitter

I'm picturing giant space lasers. Am I right?

This is the first ever such experiment, sort of the optical equivalent of Galvani's.

Nathaniel Yep.

In this case, we can see a laser sintering machine developed by EOS.

Giant space lasers? That sounds cool.

He was struggling to explain something to me a beautiful experiment that uses lasers to cool down matter.

It's interesting.

Yes we can.

At your fingers is the weaponry, the lasers, photon bolts...

Deduce the positions of the balls by firing lasers

E Spaceship noise

So what do I do? I figure I have two options.

Switch Ball or Shoot Laser

And the atoms themselves are quite violent, but if you fire lasers that are precisely tuned to the right frequency, an atom will briefly absorb those photons and tend to slow down.

Oh, don't worry about it, he said.
