Lighting Cigarette with a Laser - Smarter Every Day 37

2m read
·Nov 3, 2024

So, hey, it's me, Destin. Welcome to Smarter Every Day. I do a YouTube show.

  • Okay, well, that's so cool.

(Destin) Yeah.

  • She's like, "What do I have to..."

  • Hello! [Destin laughs]

(Destin) We're here with Johan's roommate and friend.

  • Yeah.

And we're going to... I don't condone smoking, ever. However, Johan's roommate smokes, and we're going to light her cigarette with a high powered laser. Because we... because we can, really. Goggle up.

  • The professional's here, so...

(Destin) Are you ready? Everyone have goggles?

  • Yeah.

(Destin) Okay, you come to this side. Okay. Yep, hold on, are you powering up? Hold on, let me step over the beam.

  • [Speaks Dutch]

(Destin) Okay.

  • [Speaks Dutch]

(Johan) [Unintelligible]

(Destin) Yeah.

(Johan) ...High power.

(Johan) [Speaks Dutch]

  • Oh.

(Johan) [Speaks Dutch]

  • Oh, nice!

(Destin) Yeah. [Conversation in Dutch]

(Destin) Yeah, there you go.

  • [Speaks Dutch]

(Destin) There you go.

(Johan) [Speaks Dutch]

(Destin) Smoking is wrong. [Everybody laughs]

(Destin) Did it work?

  • Yeah, nice! [Destin and girl laugh]

(Johan) [Mutters in Dutch]

(Destin) Alright. There you have it. That's how a physicist and an engineer light cigarettes that they don't smoke, in the Netherlands. [Girl laughs] Thumbs up, Johan. [Destin laughs]

Let's see.

(Johan) This is where it gets silly. If I rotate the block...

(Destin) Yeah, hold on. It's hard to adjust the focus ring at the same time. Hold the goggles please. There we go.

Holland or the Netherlands?

  • You can actually use both.

  • Really?

  • Yeah. I usually say the Netherlands. It's, uh... it's like, more professional than "we're in Holland!" [Destin laughs]

[Music]
