Based on the provided YouTube video snippets, it is possible to infer some characteristics of quicksand, although a complete definition isn't available.
Here's what can be gathered:
- Quicksand can be dangerous, with some pits being responsible for over 100 "doubts" (presumably meaning dangerous situations or incidents).
- It is possible to float on quicksand.
- Laying on your back is important in quicksand situations. This suggests it's a survival technique to increase buoyancy and prevent sinking.
From these points, we can define a quicksand pit as a dangerous type of ground or area that can cause sinking, but upon which it is possible to float, and where laying on your back is a survival technique.
