Okay, I found a bunch of reliable sources and verified some of the facts in the page summary. I also created and verified the the "OMNIMAX Theater" section. My sources were about.com and greatscience.com. I hope this is okay, I'm not trying to be a vandalize Wikipedia. Unibrow1994 ( talk) 17:36, 18 September 2010 (UTC) reply

Hello fellow Wikipedians,

I have just added archive links to 2 external links on Great Lakes Science Center. Please take a moment to review my edit. If necessary, add {{ cbignore}} after the link to keep me from modifying it. Alternatively, you can add {{ nobots|deny=InternetArchiveBot}} to keep me off the page altogether. I made the following changes:

• Added archive http://web.archive.org/web/20100922030918/http://greatscience.com/visit/exhibits.php to http://www.greatscience.com/visit/exhibits.php
• Added archive http://web.archive.org/web/20100922060052/http://greatscience.com/visit/omnihome.php to http://www.greatscience.com/visit/omnihome.php

When you have finished reviewing my changes, please set the checked parameter below to true or failed to let others know (documentation at {{ Sourcecheck}}).
