I see photos all the time of someone holding a glowing light bulb - is there a trick to this other than cloning out the wires later?

The easiest way to do it is to have a bulb lit directly behind the one in your hand.

There are 3 lightbulbs, each connected to their own switch outside a room. You are outside the room, the door is closed. The goal is to find out which switch is connected to which lightbulb. You are allowed to play with the light switches, but you can't see which switch turns on which light. You are allowed to enter the room once.

How do you figure out which switch controls which lightbulb? (I know the answer.. i'm just testing you) sorry.. the thread reminded me of this puzzle, which is actually an interview question used by consulting firms.

Do you turn one on for a bit, then off, turn the next one on and leave on, enter room... feel which off one is warmer (of the two that are off), and notice which is on and which is off and colder to figure out each of the three?

Yeah, but the lightbulb test gets even tougher when you don't know what position the switch is in. (Meaning you don't know if it's on or off!)

So back to the secret of magic lightbulbs in photography... that is clever!

If you're told they're all off to begin with, turn one on for, say, a minute, and turn it off. Turn another one on for a minute, turn it off.

Then go feel all three. The coldest is the one you didn't touch, and the warm but not hot one is the first one, and the hot one is the second one.

From trick stores, or online you can get a battery operated light bulb that looks just like a real one.

mmm, what about turning on one switch a minute, the second one 30 secs while leaving the third one off. Then going into the room and touch the bulbs (carefully), the hot one is #1, ther warm one is #2 and the cold one is #3.

[oops! too slow to read all the comments on the thread]

Nice idea the trick bulb, I will use it sometime.

Shortcut to the puzzle... enter the room with a hammer. After a few sceonds, you can [correctly] proclaim that NONE of the switches turns on any of the bulbs.

For the light bulb test question, I suggest showing how you're a team player: enter the room and ask someone else to flip the switches...

The best part of this link is the "remote control fart machine" that is available from the same site!

Oh sure, light blubs in your hand is pretty cool - but think of the photos that remote control will bring!

Thanks for the tip and the link -

Since the OP's question is already answered, here's a little hijacky...

A friend of mine got that fart machine and brought it to work. He put it on his desk and every time he pulled down a menu in Microsoft Word, the fart machine went off. He was the only one in the office with a fart machine (oddly enough) and there was only one remote activator, which I was holding. We tested it over and over and every time he opened a Word menu, it went off. Nothing else we tried on the computer would activate it.

Even though I saw it and heard it with my own eyes and ears (respectively), I still had trouble believing that something like this could activate an electronic device. Does anyone know any scientific principles that could show why this is possible or impossible?
