Shabbat 146: Eve's Contamination of Humans, Barrels, Exceptions to Stringencies

A brief look at today's daf:

Did Eve contaminate all humans when she ate from the Tree of Knowledge? Was she infected with moral contamination?  Was this a sexual act?  At Mount Sinai, did Jews become uncontaminated?  Just some questions to begin today's daf.

A new Mishna speaks of whether or not it is permitted to break a barrel so that one can eat dried figs from it. The rabbis are careful about what is permitted and what is not to ensure that extra holes are not created in barrels that hold food or drink.  For example, if one applies wax to a newly broken plug in a barrel, one could come to smooth the wax.  Smoothing is muktza.  

The Gemara speaks about the packaging of figs for a good period of time.  The rabbis also speak of how to open a barrel.  And how can a hole be repaired?  What if a chicken enclosure has a hole in it and predators might get in?  

A second new Mishna speaks of a cooked dish placed into an empty pit on Shabbat to protect the heat.  Are we permitted to change water temperature inside a pot by surrounding it with a different water temperature outside of the pot?  Further, one whose garments fell into the water while walking is permitted to replace them and continue walking until there is a place leave them to dry.  There is no fear of wringing or washing.  However, a person is not to do this if there are lots of people around, because they might suspect this person of laundering on Shabbat.
