CSO
Participated the Onizuka Science Day 2008 
Onizuka Science Day
was
held on 26th of January 2008. At the CSO booth, we had a small
parabolic dish
demonstration to show how a telescope collect radiation from distant
astronomical objects, and Walter Steiger's vacuum system that
demonstrates how light and sound would be affected in vacuum
system. For the small parabolic dish
demonstration, by dropping a ping-pong ball down on the good surface of
the
parabolic dish which sat against the gravity, people learned the ball
was bounced up at the focus position always. For the parabolic
dish demonstration, we used the 1.2 m parabolic dish donated by Oceanic
Time Warner
Cable located in Hilo in 2006. We are so grateful for their warm
hearted
donation and their support for our public educational outreach efforts.
This year, Steve Baca, Diana Bisel, Ed Bufil, Riley Ceria, and Hiroko
Shinnaga participated the Onizuka Science Day from the CSO.

presenting light and sound
would be affected in vacuum space.
