Original Reddit post

I’ll go first. Saw a street magician do this years ago and it genuinely changed how I approach meeting people. He walked up to a girl, handed her his phone with a calculator open. Asked her to type in her birthday, a time that meant something to her, a few digits from her passcode. She had total control. Then he looked her in the eyes for a few seconds and said: “That’s my phone number. Call it.” She called it. He picked up. She was completely speechless. I spent way too long figuring out how it worked. The short version: it’s called a calculator force. You design the math so that no matter what someone types in, the result always lands on the same number. Their inputs feel completely free. They’re not. The old methods were unreliable though — they depended on bugs in specific calculator versions that kept getting patched. So I eventually built my own app that does it properly. Looks like a completely normal calculator, nothing suspicious. You load your number in beforehand, hand them the phone, and the math handles the rest. Used it at bars, at a coffee shop, at a house party. The reaction is always the same — that two-second pause where you can see them trying to process what just happened. That window is everything. I’m now married, and no I won’t say more than that. What about you guys — what’s the most memorable way you’ve ever given someone your number? submitted by /u/Glass_Beautiful_6819
