Neutrino Detection
Neutrinos are elusive. A low energy neutrino has some chance of passing through 1000 light-years of lead without interacting!

Cosmic Gall
-John Updike-
Neutrinos, they are very small.
They have no charge and have no mass
And do not interact at all.
The earth is just a silly ball
To them, through which they simply pass, Like dustmaids through a drafty hall
Or photons through a sheet of glass. They snub the most exquisite gas,
Ignore the most substantial wall, Cold-shoulder steel and sounding brass,
Insult the stallion in his stall,And scorning barriers of class,
Infiltrate you and me! Like tall And painless guillotines,
they fall Down through our heads into the grass.
At night, they enter at Nepal
And pierce the lover and his lass
From underneath the bed-you call
It wonderful; I call it crass.

The New Yorker Magazine, Inc. , 1960
YOU are now being invaded by about 1014 neutrinos each second!
