Observations
This is interesting primarily in that most of us have not seen a lit filament jiggling. Beyond that it is interesting to watch the dynamics of the spring as it moves.
Today we have another shot that comes from our Shot Suggestion page. The Incandescent light bulb explosion was proposed by Cameron, and a good suggestion it was.
Materials
250Watt Heat Lamp bulb.
A spray bottle with cold water.
Procedure
I turned the bulb on and let it heat for approximately half an hour then sprayed it with water.
Result
The explosion was quite surprising in its violence. It doesn’t appear that way in the video, but the pieces flew better than six feet. Much to my dismay as I had to clean it up!
Observations
The force of the explosion was indeed quite surprising, I did not expect the pieces to fly so far. The smoke that begins to broil up was not unexpected though cooler than I had anticipated. Also, as one can see in the video, considerably brighter than I had expected. I will redo this shot during daylight to really allow the smoke to be seen as it is awfully pretty to watch live. I apologize for the smoke being so blown out, I had balanced the shot based on the light on the top of the glass. It should have been obvious that against a whitish smoke it would blow out. At any rate, enjoy!
