If you are looking for the perfect prank to play on April Fool's day, or for any reason, look no further than your own kitchen for supplies. Fake bird poop is a simple mixture of two nontoxic ingredients that you can splatter onto surfaces such as windows, cars and door handles to fool people --- without leaving any lasting damage.
Measure a cup of whipped cream with a measuring cup and dump it into a small mixing bowl.
Measure a quarter cup of black pepper and mix it into the whipped cream in the mixing bowl with a whisk. The mixture should appear grey and chalky like bird poop.
Squeeze the bulb of a turkey baster and stick the tip into the mixture. Release the bulb to allow the mixture to suck up into the baster.
Squeeze the bulb while pointing the tip of the baster at the surface you want to cover with fake bird poop. This creates a splatter effect, which looks more realistic than just scooping it onto the surface.
