Today I lost my keys in a storm drain [insert embarrassment emoji here]. This is not directly in the street but attached to a building.
Unfortunately, it is impossible to open the drain either from above or to get to it from the basement of the building. Fortunately, the drain does not really drain very much, so its bottom is of cement and I can perfectly see down through it. I can see my keys! They are two meters down below, mixed with rubbish.
The drain is just like any other, e.g.:
The space between bars is around 1.5 to 2 cm.
How can I recover them? Any clever idea? I got some but I would like to know what people come up to.
