Nuclear-secrets.com

nuclear-secrets.com is a website that Homer visits for information on how to build a nuclear reactor.

The front page of nuclear-secrets.com has a picture of Albert Einstein with several Rutherford atom symbols. The site asks two questions of visitors before they can get to the technical data: Homer finds the site to be very useful. It has plenty of information, and he uses it to build a small functioning nuclear reactor for Lisa to take to her science fair. Homer also uses the mini-reactor to threaten Goose Gladwell into giving Bart his fair share of the money from the sale of Bart's novelty T-short line to Disney.
 * "Are you a terrorist?" Homer types "NO."
 * "Would you like to meet someone special but are tired of the bar scene?" Homer types "NO," and says out loud, "I will never tire of the bar scene!"

Behind the Scenes
Before the episode first aired, Matt Groening registered the domain nuclear-secrets.com, but never created a website.
