What is a good way to preserve acrylic paint in a tupperware container?

I have a bunch of extra paint that I can't get back in the bottle, it is in a tupperware container. Is it bad to refrigerate it, or should i just seal it and leave it out?What is a good way to preserve acrylic paint in a tupperware container?
Wet a paper towel and put the paint on that then seal it in the tupperware. It's a good idea to keep the paint on a wet paper towel so it doesn't dry to fast on you while your painting. You can refrigerate it.What is a good way to preserve acrylic paint in a tupperware container?
you can leave in container for tomorrow, would be wise to add damp sponge or watered down cloth/ paper towel to help keep moist, may not be ok to place in fridge, if too cold may cause crystallization (freezer burn), and render paint with spackle specks,

It'll dry up due to the large amount of air already in the container after you've sealed it. You'll have to toss it out, it'll be dry within a week or two.
It maybe too late but for future reference. Cover pain with cellophane to surface of paint in bowl to reduce ';skinning'; peel off the next day or two and contiue painting.
