Made it to new york!

Imagine you are in a room with 3 switches. In an adjacent room there are 3 bulbs (let’s say in lamps which are on a regular table), each switch belongs to one bulb. All are off at the moment. It is impossible to see from one room to another. No help from anybody else is allowed.
How can you find out which switch belongs to which bulb, if you may enter the room with the bulbs only once?

Another burrito to add to my Chipotle shrine.

There are 9 jars filled with 100 marbles each. 8 of the 9 jars are filled with 1 gram marbles. The other jar is filled with 1.1g marbles. There is a scale with an empty jar. You are allowed to fill the empty jar with any amount of marbles from the 9 jars one time. The weight will only be calculated when you are done putting the marbles in. How do you discover which jar is filled with 1.1g marbles?
