Google gravity is where all of the google page falls down. You can still type and search stuff but when it appears it's going to fall also. While on Google gravity you can pick up the Google sign a move it around, throw it, and stack them.
Another one is Google Chuck Norris. Every time you type in Chuck Norris this screen will pop up saying Google won't search for Chuck Norris because it knows you don't find Chuck Norris, he
finds you.
There is also one Google trick called Weenie Google it's were the Google logo gets smaller as your on it
