A nice handfull of Vasoline, spread on the front and rear windscreen, will be just as frustrating, without resorting to being an actual Vandal.....feel free to add styrofoam BBs, glittery mylar shapes, stripper sparkles, etc. .....which brings up another point.....one of those 1oz vials of stripper sparkle (glitter) poured down the cowling inlets can be real interesting too. TIP: Carry latex gloves...I always have some in the console
