Buried

A few weekends ago, I went to the beach at night with my friends.  We were playing around and they decided that they wanted to bury me in the sand.  They had to pack the sand down on my body, so that I would not be able to get up.  As I was under the sand, it felt heavier and heavier each time they packed it down.  This was because of the forces acting upon my body.  First there was the force of gravity, setting me in the ground.  Second, was the weight of the sand on my body. Third, the weight of my friend pushing down to pack the sand in. Fourth was the sand underneath me, pushing up on my body.  I never thought about it before, but fun things like being buried at the beach can be related to physics!
