Three Light Bulbs

Question

You are in a closed off room, completely bare, with one windowless door to an adjacent room. There is no way to see light of the second room.

There are three light switches on the wall in your room. They correspond to three standard light bulbs in the second room. You can flick any of the light switches any way you want.

Then you walk into the second room and you have to know which light switch corresponds to which light bulb.

How do you do it?

i'm not sure how the spoiler BBcode works so here goes:

You turn on the first light switch, leave it on for a minute or so, then turn it off and turn on the second light switch. Go to the other room. The lightbulb that's lit up is Switch #2. Then feel the two dark lightbulbs. The lightbulb that is still hot (or warm) is Switch #1. The dark, cold light bulb is Switch #3, the one you didn't touch.
