Since today is April Fool's Day I'm going to list my top ten favorite pranks ideas!
Prank #1: Fake Milk
Mix cornstarch with warm water and set in fridge until cool. Unsuspecting Fool will drink it thinking that it's milk!
Prank #2: Plastic Wrap Door
Cover a doorframe with plastic wrap! Fool will walk through and get tangled up in a plastic mess!
Prank #3: Monster In The Closet
Hide in Fool's closet before they enter the room. Let them be inside the room for a few minutes, then jump out and yell, "April Fools!"
Prank #4: Snack Time
Fill an empty mayonnaise jar with something that looks like mayo, such as greek yogurt. When Fool enters kitchen, take out mayo jar and start eating! Fool will think you are eating mayo! (This can be done in another way too: Give Fool a bowl of "yogurt" that is really mayo!)
Prank #5: Rainbow Hair
Put a few drops of your desired color food coloring into Fool's shampoo. Fool will have colorful hair!
Prank #6: Ghost In The Hallway
Tell your Fool a super scary ghost story before bed. Then, around midnight, get up and start playing creepy music. The Fool will wake up and hear the music. Put a white sheet over your head and barge into the Fool's room. The Fool will be so scared!
Prank #7: Bad Breath
Sprinkle a little garlic powder on the Fool's toothbrush. When Fool brushes his/her teeth, they will get a nasty flavor!
Prank #8: Rise And Shine
Set your Fool's alarm clock so that it is several hours ahead. Fool will wake up early in the morning and start to get ready for the day at 2 am!
Prank #9: Spicy Sandwich
Make Fool a sandwich and put on loads of hot sauce. Fool will beg for a drink, so give he/she Fake Milk (prank number one.)
Prank #10: Cold Cloth
While Fool is sleeping, put a cold, wet washcloth on Fool's neck. Fool will freak out!
