Have you tried turning the LED round?
the C's in series? is the switch in series? May seem like a simple thing, but a lot of people in my 8th grade science class last year for the life of them could not figure out how to wire a switch to a lightbulb. make sure you have a resistor in series with the LED or it might burn out. People say that they can explode, but I've never seen that happen, just burned out. everything in this circuit is in series...
I've had the top part of the led instantly crack off. Not explode, but it does pop
