Sotair (Destroying) - Breaking Down the 39 Melachot

Are you allowed to take a picture off of the  wall to show it to your friend on Shabbat?   What about if there's a spill in your fridge? Are  you allowed to remove one of the drawers in order   to clean it? And finally, let's say you have a  leaf in your dining room table and you want to   remove the leaf in order to create more space.  Are you allowed to do that on Shabbat? One of   the Melachot of Shabbat is the Melacha of Sotair,  which means destroying. This does not apply to the   fridge because the drawers are meant to be easily  taken out and put back in. That's part of their   function. When it comes to the pictures that are  hanging on the wall, they're very loosely hanging   on a nail. They're not considered part of the  wall, and therefore you're allowed to take them   off and put them back on. When it comes to leaves  in a dining room table, it really depends. If the   leaf is simply a board and doesn't have pegs that  firmly connect it to the other parts of the table,   then yes, you're allowed to remove it from your  table. However, if the leaf has pegs that firmly   connect it to the other parts of the table,  then you're not allowed to remove it on Shabbat.
