say you leave some for like 2 weeks in a plastic bottle will it melt the plastic ?
There are many different types of what people usually call plastic. It's best to leave acetone in its original labeled container. If for some reason you want to put it in another container, do a test first. Put some acetone on a Q-tip and rub it on the outside of the container for several seconds. If the surface feels tacky then the acetone is dissolving it. If the acetone evaporates and the surface is clean and smooth then the acetone should be safe in it. If the surface is not smooth and clean then the acetone is attacking it and over a period of time could dissolve enough of it to leak. Again, it's best to leave all chemicals in the original labeled containers.
Acetone will dissolve some plastics but not others. For example, you can use it to melt clean breaks in ABS plastic (what LEGO is made of) so you can repair them but it doesn't affect polypropylene (what DVD cases and the plastic hardware store jugs of acetone are made of).

Depends on the plastic. Some solvents don't attack certain plastics at all, others go right through. Note that you can purchase nail polish remover - which is largely acetone - in a plastic bottle.
