Google has a variety of features that are quite useful. Here are a couple:
1) 10 minute timer - or any number of minutes. If you type X minute timer into google, it starts a timer for you. If you leave the tab open, then when the timer runs out, it will beep incessantly. Since our microwave timer beeps quietly 2-3 times, it's really useful to have this annoying timer.
2) what's my ip address - Typing this into google's search box will not only pull up sites about your ip address, but will also tell you directly. At the top of the search, your external ip address is printed in big bold text.
3) hunger games mockingjay release date - or any movie. Typing a movie followed by "release date" in google's search box will tell you the release date. Similar to the ip address, it'll print the release date in big bold text at the top of the list of search results.
4) hunger games mockingjay rating - or any movie. As before, typing a movie title followed by "rating" will display it's rating. The MPAA rating appears in big bold text at the top of the search results.
5) Date of the moon landing - Some historic events will result in their date being printed at the top of the search results. Other historic events will have a small description, including the date. For example, typing "date of the end of world war 2" pops up a brief description, including the date.
6) US minimum wage - Typing this in google's search box pulls up the current US minimum wage (currently 7.25). Replace "US" with a particular state and you'll see that state's minimum wage (California - 9.00, Texas, 7.25)
7) income tax rate in Colorado 2014 - Similar to the minimum wage thing, you can get a description of income tax rate in a particular state. The response on top is an excerpt, rather than the income tax rate, but the excerpt includes the rate.
I'm sure there are tons of other things you can search for like this. Google will simply provide the information, rather than making you wade through the pages of search results to find it.
Lastly, and most importantly, everyone should experience the image search for "atari breakout". Make sure you do an image search of exactly that phrase, and it will surprise you. Do it! :D
