Alcohol on fire and roasted pencils

Revising Form2 science. Crossed the part about decolourising the leaf in alcohol. Reminds me of the time in Form2 when my group set the alcohol on fire by accident. Oops? We weren't paying attention to it at all then it caught fire. My science book got showered with alcohol and Puan Carol was fanning the fire blanket over the test tube. Duh, we all got a lengthy lecture. Well, we weren't the only group that set the alcohol ablaze. Well, we had roasted pencils that Rhema supplied us with before. Sort of the way you would roast marshmallows. Basically, Rhema did the roasting and I did the watching.
