Why do cables become twisted when pulled out

Question

This happens all the time – you have a nice roll of wire/cable/rope/hose, then you draw out the cable from one end, then it become all twisted and messy. It’s a simple phenomenon but how to describe it intuitively? Other relevant questions – to untwist the cable can you just roll it up again? Do you have to twist it as you roll? Which way to roll or twist?

Answer 1

When you roll up wire, you are introducing a 1/2 turn every loop unless you are rolling a wire in the over-under method where you are 1/2 turning then 1/2 unturning each loop. Check youtube for proper wire rollup technique.
