# 3 Bulbs and 3 Switches Puzzle

This puzzle involves trying to figure out which switch controls each of the three light bulbs in a room, with the catch that you can only enter the room once. The solution involves a clever strategy of turning switches on and off in a specific order to deduce which switch controls each bulb.

## 3 Bulbs and 3 Switches Puzzle solution

Assume that the three bulbs in the room are labeled as X, Y, and Z. To figure out which switch controls each bulb, follow these steps:

1. Turn on switch X and leave it on for 5 to 10 minutes.
2. Turn off switch X and turn on switch Y.
3. Open the door and feel the bulbs to determine which switch controls each bulb.

Based on your observations, you can conclude the following:

1. If bulb Y is on, then switch Y controls bulb Y.
2. If bulb X is warm to the touch, then switch X controls bulb X.
3. If bulb Z is cold to the touch, then switch Z controls bulb Z.

Using this method, you can determine which switch controls each bulb by only entering the room once.
