CSO
Booth on AstroDay 2007 
AstoDay 2007 was
held on 21st of April. At the CSO booth, we had a
CSO telescope art project, and a small parabolic dish
demonstration to show how a telescope collect radiation from distant
astronomical objects, and "Space and Time" project that talks about the
speed of light (electromagnetic wave). All activities were very
successful
throughout the day. For the art project, about 180
kids and
adults made their decorations. 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.
