I blogged earlier about how you can type "set timer for 5 minutes" (or any time frame) in the Chrome address bar in order to initiate an egg timer in your browser. Well now you can ask Google to " flip a coin" and "roll a die" by typing these queries or using voice input. You could possibly use this in the classroom when assigning group work, determining group roles, or trying to decide who should go go first during certain activities.
