hello this is Jeff picked up where mouse mercury
is a very dense heavy metal
its liquid at room temperature and backed its liquid down to minus 40
degrees
Fahrenheit or Celsius any material with a lighter
density than mercury should float on it as you can see here
not willing to bet that you spent many sleepless nights wondering what
salt table salt and murky would do
when they're interacted together
reporters put a few droplets have mercury in the salt
and Canada's where you would expect the
a surface tension surface area in all their
is enough to support the droplets a mercury the small droplets
we had a little bit more it creates a little puddle
and it still supports it
now all totally saturated pouring in by pounds
which is 2.2 kilograms and
it should be like pouring milk into a beloved Rice Krispies
but it doesn't do that the grains assault should be
floating like courts on the surface of the water but they're
been submerged underneath the mercury doesn't make any sense
remember that's density of salt is one
seventh a better mercury
and now or agitated and we do get some other salt granules turning
to rise to the surface but really with this
major difference in density the
mercury should his be flowing to the bottom in the salt granules shit is
really be floating to the surface but it's just not doing that
taken a lot agitations us to do this
the salt and the mercury never combine together backed everything is still
perfectly dry that you wanna have fun
show this video to your science teacher and see it
if the or she can explain I make videos about mercury so you don't have to
mess with the stuff I have lots of videos on the subject
check out my playlist there's all kinds of stuff we do with it I hope you enjoy
this video
thank you for watching
