How can I generate a brief (100) stream of random numbers, not using the computer or throwing dice? 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.
Do a long jump, measure the distance in millimeters, take it modulo 10.

Repeat 100 times.

Another idea: use clock timer that shows milliseconds, start it and then turn off after some time, look at the last digit.
