Fact: Your iPhone has a secret undo button.

Do you own an iPhone? Prepare for your mind to be blown in just six steps:

1. Open Notes.

2. Write a totally inaccurate fact.

3. Shake your phone.

4. Witness this:

No you are not, iPhone user! You are a genius.


5. Try to catch the pieces of your mind as they explode out of your ears.

6.. Sit smugly, knowing that you have robbed the blue shirts at the Genius Bar of just a little bit of their smugness today.

(It also works for copying and pasting, and you can use it in all text-based apps. You’re welcome.)
