May one pour water from cupped hands (not from a vessel) onto another person's hands for netilat yadayim?
Synopsis
The Mechaber prohibits using cupped hands as the vessel. Rabbeinu Tam permits a specific case where the first hand was washed from a vessel and then that hand pours onto the second hand. The Rema rules that the custom follows Rabbeinu Tam, but the main opinion is the strict one.
