The milk curdles.
Nothing will happen because milk is a little bit more heavier than grease and milk is colder than grease
you would have a nice cool breakcfest
if you put milk in a plant it will smell like rotten eggs and your house will be stffed with a bad smell and you will barf and you will have to move out of your house.
a plant will grow
The yellow leaves will turn in to green gradually when the plant is put back in the sun.
5 to 12 days
The plant will dry out, die, and looked rather bleached. This process is called osoprontosis.
It will die. I am pretty sure.
A plant will die for sure if it is put in a vacuum. Vacuums don't contain air, so a plant won't be able to breathe, and will therefore not survive.
When you put a penny in fresh milk nothing will happen, but if you put it in curdled milk, the penny will become shiny.
