# How can I generate a brief (100) stream of random numbers, not using the computer or throwing dice? [closed]

I am looking for a method of making random numbers that is off-line and is also independent of specialist equipment like a Geiger counter.

Dice are specialist equipment? –  Thomas Apr 23 '14 at 8:47
Flip a coin? Cards makes the most sense - although make sure to shuffle them sufficiently many times using a riffle shuffle (other shuffles are either equivalent or worse) to ensure propper randomisation –  figlesquidge Apr 23 '14 at 8:55
What kind of number? 0/1? 1..6? π? –  CL. Apr 23 '14 at 9:20
Do you expect cryptographically secure randomness, or merely some pseudo-random numbers? Do you assume the human brain to be “specialist equipment” or not? How will you solve the issue that an averagely trained human brain can not remember a sequence of 100 random numbers? Fun aside – your question is a mixture between “not a real question” and “too broad”. (I’m not sure if we even handle “lack-of-creativity” at Crypto.SE.) In the end, I decided to flag your question for being too broad. –  e-sushi Apr 23 '14 at 19:33
