Have you ever felt betrayed by your own mind? This feeling usually engulfs us when our mind makes us do or say something that is psychologically predictable, pushing us to question how much control we really have on our brains. Or is it our brain that controls us? Use these tricks on your friends and find out what they think!

1. Ask your friend the following questions, in this order: “What’s 1+1? What’s 2+2? What’s 4+4? What’s 8+8?” Then ask them to name a vegetable. They will probably name a vegetable starting with a 'C'.

2. Whisper something to your friend. It is almost guaranteed that they will whisper back.

3. Win Rock Paper Scissors every time by asking your opponent a personal question right before you start the count. You can even interrupt the count and ask them the question. Resume the game immediately afterwards, and they will most probably throw scissors.

4. To really have some fun at the expense of your friends, start a conversation with one of them. Pick a word they say in the beginning of the conversation and give some sort of a positive affirmation (such as a smile, a nod, or even a "mhmm") each time they say that word or words close to it. This will make them say the same word very frequently.

5. Looking at the hairline of a friend while they speak will make them feel insecure.

6. Ask your friend to hold one of their hands up and think of one of one finger without telling you which one. Gently, use your finger to push against each of their fingers, one by one and feel which finger resists against your push the most; they will subconsciously put more resistance in the one they selected.

7. Sing the chorus of a song and then immediately stop and say something else that distracts your friend from the song. After some time, the song will be stuck in their head. If they hate you for it, tell them to listen to or sing the end of the song. This will fix the problem immediately!
