Instead of saving for my kids' college, I make videos using the money I would have saved.
The thought is it will help educate the world as a whole, and one day generate enough revenue to pay for their education. Until then if you appreciate what you've learned in this video and the effort that went in to it, please share the video.

Hey Destin, i think you should revisit this with some more detail and experimentation. Everyone loves lazors, but i feel this could have some more fascinating explanations and information added on. Just an idea bro!

[geckoman]

13 years later, here I am. You have come a long way!

[anotherKyle]

[SatayBeef]

I always feel happy after watching your videos

[Ylop]

i don't remember when i subscribed this channel, but I CERTAINLY DON'T REGRET IT

[NOLAMarathon]

I'm always amazed at the number of non-native-English speakers who actually speak English very well. Needless to say, Johan is one!

[marylagua]

You must have understood what he said in Dutch very impressive.

[borisesquilotromp]

I am from the Netherland and I think It sound really funny when we talk engels.

[wesleymercer]

Dude, in every video he is in a different place.

[Bromar]

So here you said you have 2% of the light going out of the mirror and 98% reflecting back; is there an optimal "imperfection" for the mirror to have the strongest laser with only changing the mirror?

[stevebrtr]

Nice to see you in my country :D
Have fun during your stay.
Maybe we can meat up and ill teach you some juggling :D

[kittyria]

How are you always traveling? Each video, practically, seems to be from a different country.

[SuperDrummerful]

Me - 'lets fire this baby up!' *click*
Me - hey? why it not working?? *looks down tube*

Photon torpedo is Star Trek not Star Wars

[Illendor]

& ja ik spreek nederlands :p lol

[MassTrader]

But photon torpedoes are from Star Wars--

[TsuiIzumi]

A laser could cause a steam explosion?

[_davver]

98% of the photons get reflected. We're the 2% that don't. #OCCUPYMIRROR.
