Hello, this is Deguchi.

On May 31st, PET bottle rocket seminar was held at Fukuoka Elementary School.

The weather was very good. It was good day to launch PET bottle rockets. And Takahashi-kun's head was shining.

Now, my job in the day was to keep watch the launch mount of PET bottle rocket. It was very important job. Maybe.

Because I had enough time, I improved a PET bottle rocket by trial and error to win children.

But on the one hand, children's PET bottle rocket flew off through the air forming beautiful parabolic trajectories, on the other hand My rocket was stalled immediately, and got crashed to the ground.

Every children had pleased look in success lauching their rockets. At that time, I knew the fact that childran's pure mind made their rockets flown a long distance. It is important to have a passion for own PET bottle rocket.

This seminar turned out to be extremely successful. I think that children felt the fun of science. And I learnd very important thing too.
