Main Question or Discussion Point

Hello, everyone. I have a project for science fair that I would like to do, but I need verification to see if this will work like I think it will.

My experiment's name is "The Effects of Electricity and Configuration on an Electrochemical Cell". It's wordy, but what can I do? Anyhow, my experiment is to first build a galvanic cell by using a zinc electrode, a copper electrode, a 1 M solution of copper (II) sulfate, and a 1 M solution of zinc sulfate. I'm going to use instead of a salt bridge a porous cup, and I'm measuring my voltage (should be 1.1 volts) with a voltmeter. The reaction in this cell should plate copper on the copper electrode and dissolve away the zinc electrode. My experiment is to see if I can reverse this process by adding electricity.

Basically, I'm going to start with a fresh set of electrodes and solutions, identical to the ones I used in my galvanic cell. But, this time, instead of a voltmeter, I'm inserting a 12V hobby battery into the mixture. I'm connecting the positive end to the zinc electrode.

What I would like to know is "Will this do something unforseeably dangerous?" and "How quick is this reaction going to take place?" If I add more energy, will it speed up the process? I'm only in the 9th grade, so I haven't taken chemistry yet, so please help! Thanks.
