    That's awesome but nobody explains how long it takes to leave the round bottom flask on top and how long it takes to form crystals?

    Is it real gold or just looks like gold?!

    It looks like gold since it is a yellow precipitate. A double displacement reaction is taking place here forming a yellow precipitate aka lead iodide

    I repeated these instructions to the letter. (I used 12.5 mL of 1.6 M H2SO4 and I diluted 1 mL of 30%H2O2 to 10 mL but otherwise, exact). I mixed the solutions and ... nothing. After about 4-5 minutes of swirling I noticed the solution turn a light yellow. The color gradually turned a deep amber. The only point that might have introduced error was the vaguely-named "starch solution." Not knowing the precise composition, I made a small amount of solution from Aldrich's "Water soluble Starch" as a saturated solution in distilled water. Was this what was needed or was that my mistake? Have fun and good luck. My clock is still ticking.
