I really won't suggest doing lab works at home, stuff that really increase your skills often involve using materials you don't want to accidentally spill on your carpet. Two things that I would DEFINITELY suggest for you to practice on are pipetting and burette reading, both of which involves equipments that you can't find just anywhere, and are both ever-so-useful to familiarize yourself with.
I'd suggest going to a local university or collage and ask for permission to use one of their lab rooms, under supervision of course, to practice these skills. Be prepared for some difficulty in booking a room, and forking over some green, but these lab technicians can help you in ways you can't imagine.
If you don't happen to live beside a university or collage, just try doing some research to find a lab near you, sometimes a hospital might be nice enough to let you go in.
All in all, don't do experiments at home, these kinds of experiments are all half-play, and don't present the situations you're going to face in a real lab. If you're serious in getting some real lab experience, go for a real lab.
p.s. If you did manage to get yourself a lab remember this, when pipetting, plug the top with your INDEX FINGER, NOT YOUR THUMB!! I cannot stress this enough, I've seen more than one instances of people who fell with their thumb on their pipette and ended up getting a piece of glass pipette embedded in their flesh.
