I know it is a joke but that is a very conservative number of neutrinos....
I found this...
The number of particles crossing a 1 m2 plane is just the number density (in #/m^3) times the velocity (in m/s). There are 150,000,000 neutrinos per cubic meter, and they're moving at about 3,935,435.55 meters per second, for a grand total of 5.90315332 * 1014 crossing a one-meter square area per second. Quite a lot!
The only problem is I can not track down who said this first ...
I guess the up side is you would not have to give away very large box to give a couple of
million
