Steps

Step 1: Execute a Sneak Attack

Find a moment when your sister is deeply focused—playing a game, drawing, or chatting on the phone. Quietly creep up behind her, staying out of sight. When you’re close enough, yell “Boo!” or make a loud noise. Her startled reaction will be worth it! For extra points, try this when she doesn’t even know you’re home—she’ll never see it coming.

Step 2: Turn Off the Lights

Wait until she thinks she’s alone or you’re asleep. Sneak your hand into her room and flip off the lights, plunging her into darkness. She’ll likely scream, wondering what happened. If she knows you’re around, pretend to be busy elsewhere—like reading a book—so she doesn’t suspect you. Alternatively, wear a spooky costume and shine a flashlight on your face from across the room for a dramatic scare.

Step 3: Pretend to Sleep, Then Jump Up

During a car ride or while lounging together, close your eyes and act like you’re napping. Wait until she gets close—maybe to check if you’re really asleep—then suddenly open your eyes wide and yell. The surprise factor will catch her off guard, making it a simple yet effective scare.

Step 4: Tell a Chilling Story

Invite a friend over and start telling ghost stories. When your sister wants to join, act hesitant, saying the tales might be too scary for her. After she insists, “reluctantly” share a creepy story tied to an object in your home—like a haunted doll or eerie photo. Later, sneak that object into her room while she sleeps and wait for her terrified reaction.

Step 5: Wear a Clown Mask

If your sister fears clowns (many kids do!), grab a clown mask. Position yourself somewhere unexpected—like in a chair facing away from her when she walks in. When she approaches, turn around with the mask on and watch her jump. Timing is key—catch her off guard for maximum effect.

Step 6: Use Fake Bugs

Pick up some realistic fake bugs from a novelty store. Place them in surprising spots: her backpack, pillow, or even the sink. She’ll shriek when she spots them, especially if she hates creepy crawlies. Bonus: you might not see her reaction, but the setup is still a win.

Step 7: Tap on Her Window

For a bolder move, tap on her window at night. Use pebbles or a stick for a eerie sound, then dash back to your room and act innocent. Safety first—only try this if you can move around securely outside. The mysterious noise will leave her spooked!

Step 8: Hide in a Box by the Door

Get a large box, place it outside your front door, and ring the bell when she’s home alone. Quickly hop inside and wait. When she opens the door and peers at the box, leap out with a scream. It’s a classic prank that’s sure to get a big reaction.

Step 9: Ambush from the Closet

Hide in a closet and call your sister, pretending you’re elsewhere. Ask her to grab something from the closet for you. When she opens the door, jump out! This works best if she’s willing to help you out—her confusion will amplify the scare.

Step 10: Swap Her Desktop Background

When she steps away from her computer or phone, change the background to something creepy—like a ghostly image or spooky face. She’ll be startled when she returns. Keep it simple and not too terrifying to avoid real upset.

Step 11: Drop a Fake Spider

Attach a fake spider to a clear string or fishing line. From a distance—like outside her window or over a tree branch—lower it near her as she passes by. The sudden “attack” will have her screaming before she realizes it’s fake.

Step 12: Leap from the Bushes

Hide behind a bush when you know she’ll walk by. As she approaches, jump out with a shout. Keep it basic or add a mask for extra flair. Snap a quick photo of her reaction if you can—it’s a memory worth keeping!

Step 13: Tickle Her Neck with a Feather

Sneak up with a feather while she’s distracted. Lightly brush the back of her neck, then hide or step back fast. She’ll freak out at the unexplained sensation, especially if you vanish before she turns around.

Step 14: Hide a Fake Snake in Her Bed

Slip a realistic fake snake under her covers or on her pillow when she’s not looking. When she climbs into bed, her scream will echo through the house. Make sure it’s hidden just enough to surprise her.

Step 15: Appear in the Mirror

If she’s primping in front of a mirror, put on a scary mask or smear fake blood on your face. Creep up behind her silently—when she spots your reflection, she’ll lose it. Timing and stealth are crucial here.

Step 16: Plant a Scary Object While She Sleeps

After she’s asleep, place something spooky in her bed—like a fake head, giant bug, or snake. Position it so it’s the first thing she sees upon waking. She’ll wake up startled, giving you a perfect prank payoff.
