Fan and tooth brush prank
OK for the 1st fan prank get confetti or flour and put it on the blades of the ceiling fan when the victim turns it on they will be in for a surprise and sprinkled with confetti or flour.
2nd prank: The tooth brush prank. Get you victims toothbrush and sprinkle salt or a sour juice on it and then put oraljel or teejel (which is clear and used to soothe baby teething pain and other tooth aches) into the tooth paste or into the tooth brush so there mouth goes numb, now wait for the victim to brush there teeth and bam! It taste horrible and then there mouth will go numb :D But make sure you do it to a older person its bad to swallow oraljel (I don't know how to spell it) lol :D
