Today I learnt how to light a bunsen burner during chemistry class. Here's how!

1. Wear your safety goggles.
2. Connect rubber tube to gas tap.
3. Make sure there is no hole in the bunsen burner. If there is a gap, close it.
4. Slowly turn on the gas tap.
5. Check that you hear a sound coming from the bunsen burner.
6. Hold the flame igniter right at the tip of the bunsen burner. Make sure that it is not locked.
7. Press the flame igniter to light up the bunsen burner.
8. When a flame comes out, it should look mainly orange. 
9. As you turn the thing to create a hole, the flame should turn blueish and almost invisible.
10. When you want to turn of the bunsen burner, close the gap first.
11. Then switch off the tap carefully.

Different areas of the flame will have different temperatures. The part right a the tip of the bunsen burner itself is the least hottest. The one in the middle is the hottest and the top part of the flame is in between.
