Sample answer:

Well, I remember when I was in senior high, our chemistry teacher told us that coke can be used to clean the kitchen, because the acidic chemicals in coke can dissolve the dirt. I tried it and it really worked! I mean, I poured a small amount of coke in the kitchen where the dirt was hidden, and after soaking for a few minutes, the dirt gradually dissolved, which was truly amazing!
