Turning lead into gold (lead iodide)

Ok, so today I'm going to try to turn some lead into gold. The first step is to get a few pieces of
lead, and to add some dilute nitric acid. What I have to do next is get a beaker, and add some boiling water, and a small amount of potassium iodide. This all dissolves really quickly, and on top of
this, I'll add a bit of vinegar, and that little lead solution from before. Now all I need to do
is turn off the stirring, and basically just wait.

Ingredients:
1) 0.5g lead metal + 50:50 nitric acid:water
2) 500mL water, 1g potassium iodide, 5% vinegar
3) Profit?
