Solar water heaters are used around the world and they are not difficult to make. They were invented many years ago. The solar water heater can heat 70 liters of water to 63 degrees in six hours. When exposed to the sun, black surfaces are hotter than other colors, so water in the storage tank will become hot. Besides, there are two rubber pipes attach to the water heater, and one of them/the pipes lets water flow in the storage tank, and the other one lets water flow out.

I don’t know whether i miss being a student or not. Because both have advantages and advantagess. To students, they don’t have any pressures in their life and they always focus on their studies and play , includes they have summe and winter breaks. But being students also has disadvantages, they don’t have money that belongs to themselves, so they can’t buy something they want. Although adults have some pressures in their life and work, they have enough money to do some interesting things they like,they don’t need to their parents’ approve. Apart from that, they don’t know some things which were happened in the future, but adults can work harder to earn money to pursue their life they want.
