These very short videos are showing, that the sand and powder can behave sometimes like fluid and sometimes like solid. 1.01 – Pile and weightThe video shows that the sand can be poured like liquid, but when poured creates a slopy pile, which can support a strong load. 1.02 – SaltshakersParadox: the water has problems
