BAFTA winning TV / Film comedy writers, Jon and James are currently writing a new feature film for Entertainment One and Big Talk.

They've just finished filming their original six-part sitcom WASTED for E4 which airs this summer.

Previously they've written on CUCKOO for BBC One and co-wrote THE HARRY HILL MOVIE with Harry Hill. They were lead writers on the first two seasons of THE AMAZING WORLD OF GUMBALL for Cartoon Network for which they won writer's BAFTAs in 2011, 2012 and 2013. They were also on the writing team for PADDINGTON, GRIMSBY and ARMSTRONG AND MILLER.

Real Actual Science

A mate of mine called Richie Hanes is a real actual scientist
working in Dusseldorf moving atoms around with
state of the art hene lazers. It's pretty fucking cool.

Heres a video of his, though I dont pretend to know
anything about the mechanics of it, essentially he's
using lazers to change ionic charges and then move particles
around as if he was holding them in a pair of tweezers.

Please corret me if I'm wrong Rich. And I'd love you to explain it
properly on here if you have time.

In this video its 4┬Ám Latex Spheres in Water Trapped using a 17mw hene Laser.
You go girl!

  1. Safety safe ob, thanks for adding me to your blog. I made this video about 2 1/2 years ago and it is the first incantation of what is now a fairly sophisticated set-up. The physics behind how it works goes like this:

    If you take a material which has some mobile charges (electrons or positive ions) and you put it in a electric field, it becomes polarised. That is, the negative charges in the material move to the more positive end of the field and vice versa. The material now has a charge gradient across it, with one side being more negative and the other positive. If the applied electric field does not have the same intensity everywhere, but, lets say, is stronger on the negative side of the material, then the attraction between this side of the material and the positive field will be stronger than the attraction between the positive side of the material and the negative field. So the material feels a force pushing it towards the higher intensity field. It's a bit like a tug of war, if there is a stronger team on one side, the rope moves in that direction.

    How does that relate here? Well, light is a wave in the electromagnetic field, meaning it has an electric field part and a magnetic part. Lets forget about the magnetic part for now and concentrate on the electric part. If you focus a laser beam, like the red dot in the movie, then you have an electric field with the highest intensity right in the middle of the spot. The particles are little plastic spheres, and they are polarised by the electric field of the light. Now, because the field is strongest in the middle of the beam, that is where the particle is drawn to, and when it gets there, it sits in the centre of this field and feels an equal force in all direction, so it stays still. Now when you move the beam, you are moving the high intensity bit of the field, so the particle feels a force which pulls it back. In this way, you can apply a force to these particles without actually touching them, essentially tweezing them with light.

    hope this helps,

    safety safe
