Optical Trapping

[Things]

Most of you would know about it, but I managed to snap some really good pictures of it. They are 3264x2448 jpg's, so I cant put them here directly, so here:

Hey Dan, that's really cool. It's not the easiest thing to photograph. Usually by the time you've got the camera ready the effect has gone.

Great Job!

I pretty much shut up the room, blocked my laptop exhaust, breathed downwards and moved very slowly, and the laser was inside a half-sealed box. I managed to get a bit trapped for over 1 minute doing this.

Thanks

I'm not sure what that is. My wild guess is that your levitating a speck of dust.

That's cool, what did you use as a seed? Looks to be some sort of fibrous material, I've read that plastics work well.

I burnt the tip of a black felt pen, so yeah, some sort of fiber. And essentially it's just wedged in the focal point of the laser.
