Bulbie Experimental Shots

I had time after I got home from camp on Saturday, so I bought 4 light bulbs for some experimental shoot. I had previously seen this idea on some photography galleries, and decided to try it out on my own.

 

This is how the lightbulb lits up. Nothing special.

 

And what happens when the glass is broken? It burns!

And with a little photoshopping, you get a clearer observation of how the fume diffuses.

Cool? Now, anyone can explain this phenomenon in terms of science? :P
