my uncle was a postman, when I young he used to give me as many rubber bands as I needed, from memory they were brown I made a daisy chain of rubber bands that - when stetched, was about 400meters long (to the end of our street). When i let it go, I thought something crazy would happen (i was about 6-7)but in reality nothing really happened it just shrank fast I was extremely disapointed, it look many days to do this…
in USSR pretty much everything was in shortage, including rubber bands, and when you got your hands on it, you'd do something like "rubber band motor" plane or boat like this:
