Here's how to do it:
1. Open up Notepad (not Wordpad, not Word or any other word processor)
2. Type in this sentence exactly (without quotes): "this app can break"
3. Save the file to your hard drive.
4. Close Notepad
5. Open the saved file by double clicking it.
Instead of seeing your sentence, you should see a series of squares.
