What difficulties i faced while doing the experiments?

Basically, i did not have many problems doing the experiments. I used to have problems lighting up the bunsen burner because i was afraid of the strong fire. Now, i am not at all scared to light it up because that day, i tried my very best to overcome my fears of lighting it up. I had fun lighting it up and i would really love to do it again. Please bring us to the lab more often Mr Chiang!
