I went to the Kiso-gawa River riverbed to experiment on the parachute descent by the water rocket with Mr. and Mrs. 2,010.10.6. Consecutive three times succeeded for the first time. It was 1/3 establishment before.When it was the main cause that speed received the parachute is caught in a trunk, and to open is late, it understands a rocket leader that the parachute the does not readily open. I largely shortened a trunk as measures, but an experiment was late and was not able to give a result. The help of the wife was necessary by all means without can carry a water rocket and a launching pad to the riverbed with I alone. Because the cloth of the parachute used an umbrella thrown away in the field, I contributed to recycling just a little.
