what are some good scary halloween pranks?
<|assistant|>
You can hide in a room and scare people when they open the door, put a few drops of fake blood on a car for an extra creepy effect, cover a couple of candles with a cup and put it in a room to create eerie shadows, or turn the lights on and off randomly in a certain area. Other options include playing creepy music in the background and hanging strange objects around the house. 

Halloween pranks don't have to be extreme to be effective. Simple acts like flickering a light switch at unexpected intervals can make people feel jumpy. Fake blood is inexpensive and can liven up your decor. A spooky atmosphere can be conjured simply by playing suitable music, or a collection of strange objects can be strategically placed around the home. Whatever prank you choose to attempt, be sure to stay safe and have fun!
