Twister is a fun tool from Classtools.net. Twister, like Fakebook and Fake SMS allows you to imagine what historical figures would have done if they had access to social media. Twister allows you to create fake tweets about this person and fun hashtags.   When studying famous people or reading biographies, this would be a great technology project for upper grades.
To create a fake Tweet on Twister just go to the site and enter a name, a Tweet, and date stamp for your Tweet. Twister will pull a public domain image for the profile picture and show you the fake Tweet. Your fake Tweet will be given its own URL. You can also just take a screenshot of it to save it.
