50 years ago, I was study in middle school which was disappeared after we graduated. In our class, most of my friends were older than me. We always came out new idea for joking other people or teacher, even against school. There are several things that make me impressive, such as made smoke ball. One of the most interested things is the smoke ball. We didn’t buy smoke ball from outside, the smoke ball was made by our classmates. The step for making smoke ball is very easy. First step is to get the solid paper from cigarette box, beside solid paper another thing is ping-pang; use the sewers to broke Ping-Pang, cut in pieces. Then put Ping-Pang pieces in the paper from sigrate. We can make the shape be easier to fire. The last step is fire the smoke ball and put the place where people want. Actually we putted in the teacher’s office, it was fun. I can’t exactly memory the results of that, the reason it’s about our class head teacher clacte money from students who is late, and we thought it was not fair for us. Then we did something back for fun, just like made the smoke ball.
