Concrete

Looks great. And it’s hard as a rock

pretty cool

The Flintstones movie taught me the true origin of this magnificent material, and because I support women: 5/5

We will never know what's in it

my cats name is concrete :)

terrible color and texture, ugly, ruins cities and communities

want to see the documentary

ahhhhh yes the hardest stuff on earth

works good

very underrated. it's beautiful

sometimes on the street i see concrete with the footprints of birds permanently embedded in it and i like that property of concrete. sometimes in movies & games i see that a person can be buried in concrete and i do not like that about it. a dilemma indeed

Useful for building

Problematic goat

The oldest manmade permanent structures are made of concrete. It is both literally and figuratively the foundation of civilization. -1 star for the energy required to produce.
