We have a class 4 laser. We're in Holland, and this is Johan, and he's a

laser expert, guru, whatever you want to call it.

Alright so,

You ready? -I'm ready Alright, so. We're gonna turn the laser on high power first.

-Ready? Yep

-OK there we go. OK, so

what colour is this laser Johan? This is blue in english.

-Blauw Blauw? -blauw Blauw. OK so what colour

is the first balloon? -Rood Rood, which is red? - ahuh

Here's one for you.

What colour is this? -black, or swart.

[pop] Woo! -and finally, white,

-or, wit.

OK.. What's going on here? We have a white balloon that's not popping

in the laser that popped every other colour. Would you like to explain laser guru?

-The white one scatters all the light, so it doesn't absorb the light, and

-doesn't heat, and doesn't pop. There you go. You're getting

Bing! [laugh] Get it? Light bulb.

Alright. Later. Have a good one.

You've heard of sharks with laser

beams on their heads, but ah, come on down.

The cool thing about that is the laser beam, not necessarily the shark, and even though there's shark week, we're gonna have laser month,

because that's way cool. Johan here has built this laser

It's a 445 nanometer, 3 watt, 3 diode

laser, and it is capable of burning about anything you put in it's

way, depending on it's colour. And, we are going to do laser month.
