It's 21:30, you've had a bit of the runs and managed to block your toilet with overenthusiastic usage of toilet paper. You have no plunger and an Evil Overflow Event is lurking. What do you do?
The coathanger wire/cable fishing rod technique didn't result in any positive outcome, the guts were rumbling loudly again and so I started thinking urgently about improvising a plunger. The pack rat in me compared the toilet trap shape with all the things at or around home, and there you are: the bottom of an empty two liter softdrink bottle looks close. Two minutes of vigorous plunging and some splashing later and all was well.
