I'm Sato. Hello. On July 20th, PET bottle rocket class was held at Yoshioka elementary school, we participated in the event and helped children to make PET bottle rockets. A typhoon was approaching, but it was safely held event.

First, Prof. Maruyama explained "Why do rocket fly". It is action-reaction law, same as Astro Boy.

Children listened how to make pet bottle rocket deeply and very skillfully made the rocket.
The PET bottle rockets of great individuality were made by children.

It is a time to launch the rocket. It is very beautiful to fly PET bottle rockets of various colors in the sky. The rockets flew a long away to the sky, we enjoyed PET bottle rocket event so much.

I wish children find science very interesting through the event. I also had valuable experiment.
