Ever wondered how they change the massive bulbs in an IMAX projector? Find out here!

Everyone loves IMAX and there's a good reason, not only do you get world leading audio in laser configurated settings that have been tuned to perfection but you get to experience building high images projected with absolute clarity.

And those images all come from a massive IMAX projector - or sometimes two such projectors - which are throwing out an immense amount of light to keep your explosions and vistas looking as pristine as possible. The lights are powered by massive bulbs which heat to a massive degree and have to be water cooled to keep from exploding. But, like every bulb, they do blow from time to time. If you've ever wondered what happens next, check out this fascinating video which goes behind the scenes at the IMAX in San Jose's technology museum.
