So the wife went and got herself pregnant again (yes I blame her, I'm entirely innocent in this!), so we've been discussing gender reveal ideas and while I realize the gender reveal burnout has been done before, I'm up for any excuse to do a burnout...(I should buy stock in a tire company). My question is has anybody come up with a method of coloring tire smoke temporarily rather than spending $500+ on a set of one time use novelty tires?
