**How would you generate a sequence of random numbers, if you didn’t have a computer or calculator?** Each time you typ *rng default* or *random.randint*, numbers get drawn from precise observations of some natural process or special algorithms to produce sequences of numbers with certain properties of randomness. But what if your laptop died, your phone had no reception, or you’d suddenly find yourself transported 50 years back in time? How could you approximate random sampling from different distributions just using pen, paper, and whatever you could find in your house?

I thought of three categories (to start with): **A.** human-made randomization gadgets, **B.** measurement, **C.** just you in an empty room.

**Rules**: Please share your best guesses and intuitions and limitations of each method. If you know what exact distribution can be approximated with each process, please let me know – I’ll update the post as more ideas come in. *Do not Google* (or be honest if you did). Let’s play!

**Update**: see the Twitter thread for a bunch of interesting responses and suggestions – I’ve copied some of those into the list of suggestions below (no guarantees).
