The water rocket discharge party of a primary schoolchild performed on August 1 was performed this year last year in Konan Suitopia on July 10. Terrible rain fell last year and had a great experience, but I was endowed with beautiful weather this year and was lucky. A primary schoolchild third grader and the first grader of the grandchild participated, but I finished the water rocket production somehow, but there was not the competition with the fourth place. Because a body is lightweight, what is controlled by the state of the wind of the neighborhood of sky 15m of the moment when I launched it is thought about, and there seems to be the luck. According to the unofficial record of the group which I sponsored, there seems to be a flying distance of 300m. It will be 80 flying distance several meters this time to the fourth place high rank. Because I omitted an introduction video I shot a fruit because it was the hot time of the midsummer, and to hasten the time, it was able to be finished by approximately the midday. There was a case they raised inflator pressure too high in the discharge society three years ago, and to go off accidentally, but the security of the child whom I established all the inflators safety valve for accident prevention at this time and lengthened an inflator tube 2m, and fired it was planned. On this account there was no accidental discharge. It will be the disposition of the sponsor. It is the grandchildren whom I did not send to the high rank in this discharge society, but I take a consolation prize and candy, and it should be it with the one of the memories in summer.
