Quicksand consists of fine granular material, such as sand, and water. When water in the sand cannot escape, it can create a liquefied soil that loses strength and cannot support weight. It's also a surprisingly common hazard in films.
1. Lifting a submerged foot out of quicksand at a rate of 1cm/s would require a force equivalent to what?
2. Which of these would become completely submerged in quicksand?
3. In which decade of film did quicksand have its heyday, appearing in just under 3% of films (according to Slate.com)?
