The process of water purificatio

Last time we went to the lab in Nottingham and did the water purification. At first we dressed, we were ready, we put on our glasses, we looked like a doctor, and suddenly we felt great and awesome. And then we all went into the lab, and there was a lot of material in the lab. Bucket, charcoal, fine sand, coarse sand, chalk dust, etc.

And then we started trying again and again. Unfortunately, they all failed in the end. Looking at other groups, our opponents, we slowly purified the water. Almost all of us were depressed, and at that moment there was an outburst of anger in my heart. Every time I got angry, I got very angry and finally tried the method the scientists gave us. Water is becoming cleaner than the last time, but there are still a lot of impurities, and so our team leader also crazy, we are all special gas, want to anger, but, we still no vent, just arguing for a while. After that, we decided that each of us would try it his or her own way. Since I started, I only use the activated carbon, we are very much looking forward to, finally said a little white, finally forms completely turned white, then I suddenly a shout, our water finally turned white, then his silence was broken by me. I feel so ashamed, but I can't help feeling excited. The same was true for the other team members. Then we quickly took our water to test, but we didn't expect that there was only negative 0.003 impurities. Yes! Yes! Yes! I feel like our group knows one of the best achievements in the world. It's our own. No, it's not ours. It's ours. No, it's not ours. We think about it, we feel like we're awesome, because our magazine is at least one in 40 people, so we feel like we're awesome. The rest of the group envied us. They all said that we were very good. Later, scientists said that activated carbon was the most important. And the sediment, just to hold it. Because the water flow in the tunnel is so fast, it's impossible. I just put in the activated carbon, I was washed away by the water. So I feel that I have gained a lot from these lessons, from failure to success. In the last sentence, we are really awesome.
