Dear friends, today I will show you a very special invention of mine. Can you guess what that is? It is a machine that identifies whether a person using the toilet has washed the toilet, otherwise it will wash for that person, that person will not need to flush the toilet when using the toilet. The structure of that machine is a sticky sensor on the toilet seat with an odor detector. When the person sitting on it comes out, the sensor will notify the headquarters, then the machine knows the smell will determine if there is still smell or not, if there is it will wash itself. Although my invention is so good, in my team the best invention is probably the leader of the team with the invention of a handheld device to use to its original position if we throw it indiscriminately.
