Here are some big ones that should not be used at the friendly stage of a prank war.
It is surprisingly cheap to have a load of crushed stone delivered right in front of somebody’s garage.
If you can find a small access hole, you can pour in a few dozen crickets from a bait shop. The chirping is really annoying. In a few hours, two people can capture most of the crickets, but the stragglers will chirp in dark corners for weeks.
If you want to make a really sticky mess, it’s hard to beat orange soda.
Now, for the car stuff. Armor-all on the windshield won’t be noticed until it rains; then it makes a visibility problem, and it’s tough to remove.
The heater/AC intake is right in front of the windshield. Several things can be poured into that while the car is locked. An entire bottle of Axe or a cheap knockoff of some cologne will linger a long, long time. For wet weather, dish detergent. For dry weather, get a bottle of chalk-line chalk, like the carpenters use. The first blast of the blower gives a billowing cloud of white, blue, or red powder that clings to everything. If you want to be really vicious, get day-glo orange chalk, which is permanent.
Speaking of vicious, sporting goods stores sell bottles of fox urine and similar vile natural odors. Hunters squirt some around to mask their own human odor. You can fill a syringe with it and inject it through the rubber door gasket.
The Car Talk® guys described a maddening, but harmless prank that goes on for weeks. The victim gets a new car. The pranksters add a little extra fuel to his tank in the second week of the new car’s life. The victim brags about his gas mileage, and progressively larger amounts of fuel are added. More amazed bragging. Then the adding stops. The next week, fuel is subtracted, and more and more, until he’s getting 15 miles to the gallon and tearing his hair out.
I have heard of tires being glued to the ground. I don’t know how well it works.
