Unusual clip on the BBC site. It's an extract from their next Click programme which will be shown in 360-degree mode. It will be possible for you to move the view 360 degrees around and up and down. The clip is from the Hadron Collider. Details how to view it are in the article.

On a computer it's just a matter on clicking on the arrows in the top left corner. If the clip freezes just click the play button to restart.
The programme itself is being shown at 1.30 tomorrow morning on BBC News channel. It may be being shown at later times of 6.30 am, 19.30 pm, then on Sunday 3.30 am and 13.30 pm according to one page on the BBC site, but their TV Guide shows differently which is confusing. I doubt if recording it would work.
I don't know if it will get put on iPlayer.
