How to Scare Your Little Sister

Sometimes, the sharp scream of your little sister after you pull off a clever prank is the greatest joy you can experience. If you're looking for a way to get back at your sister for constantly annoying you, scaring her in a subtle and unexpected way is your best bet. As long as you don't take it too far, you'll probably succeed in giving her a good fright, and get a hearty laugh out of her reaction. If you're searching for some cool ideas to scare your sister, let's dive into Step 1.

Surprise Attack. Look for a moment when your sister is totally engrossed in something—whether she's playing a game, drawing, chatting on the phone, or doing homework. Then, sneak up behind her. Once you're close enough that she doesn’t notice you, shout "Boo!" and enjoy the startled scream that follows. Done right, this is one of the simplest and best pranks you can pull. It will work even better if she doesn’t know you're at home.

Turn Off the Lights. This method works best when your sister thinks you've decided to stay at a friend's house. Wait for the moment when she believes she's home alone, or when she's in her room, and secretly slip into her room to turn off all the lights. If you pull this off right, she'll scream in confusion, not knowing what just happened. If she knows you're at home, you could also grab a book and pretend to be reading in another room when she bursts in, yelling.

• Alternatively, you could dress in a creepy outfit and shine a flashlight at your face in a dark room. Your sister will be terrified!

Surprise her when she thinks you're in a deep sleep. If you’re both on a long trip or sitting together watching TV, pretend to doze off for a few minutes. Wait until you feel your sister getting closer to you or moving closer to your face. When she believes you're fast asleep and doesn't suspect anything, suddenly open your eyes wide and scream at the top of your lungs. If done correctly, you’ll give her quite a scare.

Tell a scary story. Invite a friend over for a spooky storytelling session. When your sister wants to join in, tell her she shouldn’t because the stories you're about to tell might be too terrifying for her. She’ll beg and plead to join, so pretend to agree. Then, before starting your story, act unsure whether you should tell it, saying it’s based on real events and might frighten her. Finally, casually mention that you’re ‘reluctantly’ going to share a tale about something in your house—like a cursed teddy bear or a mysterious old photo. Once you finish the story, both you and your friend should pretend to go to bed, then place the object from the story (like the teddy bear) in her room and wait for her scream.

Wear a clown mask. This trick only works if your sister is one of those people who gets scared by clowns. In fact, it’s more common than you think. If your sister is afraid of clowns, buy a clown mask and surprise her with it. Choose a completely unexpected moment, like when she comes home from school and sees you resting on a chair with your back turned. As she gets closer, turn around suddenly with the mask on and give her the fright of her life!

Use fake bugs to scare her. Head to a toy store and buy some fake bugs to prank your sister. Most kids are terrified of bugs at some point, so placing them in unexpected places will surely make her scream. You can hide a bug in her backpack—this will really freak her out, even if you won’t be there to hear her scream. Alternatively, place fake bugs in her pillow, the sink, her food, or anywhere she wouldn’t expect it.

Wear a mask when she thinks you’re asleep. If you plan on waking up late and your sister is assigned the task of waking you up, this is the perfect opportunity to play your prank. Put on a creepy mask—whether it’s a monster mask, a boogeyman mask, or even a clown mask—and lie down facing the wall, covered with a blanket. When your sister calls your name repeatedly to wake you up, wait until she’s close enough, and when she thinks you're sound asleep, suddenly jump up with the mask on. She’ll definitely scream, as she won’t be expecting it at all.

Knock on her window. If you want to go all out with your prank, you can knock on your sister’s window at night. While climbing onto the roof may not be the best idea, if you’re confident you can do it safely, knocking on her window in the dead of night will definitely frighten her. You can also throw pebbles at the window or use a branch to tap on it. Then, quickly return to your room and pretend to be asleep or doing homework, so she won’t suspect that you are the culprit.

Use fake blood. Fake blood is always a great tool for scaring your sister, no matter how you use it. You can let her discover you lying in bed with your face covered in fake blood. Alternatively, you can cover your entire body in fake blood and let her find you face down at the dinner table. You can even pretend that your hand got stuck in the garbage disposal and then suddenly pull it out with fake blood all over it, screaming in terror. However, be cautious with this prank, as it will *really* frighten your poor sister!

Hide in a box outside the door. This prank is definitely worth pulling off. First, you need a box big enough for you to hide inside. Then, place it outside the door when your sister is home. Ring the doorbell and quickly jump into the box. When she opens the door and stares at the box for a few moments, jump out and scream. It will make her scream too!

Sneak attack from the closet. This one is a bit trickier, but it can work wonders if done right. First, hide in the closet. Then, call your sister, pretending that you’re not at home. Tell her you need her help and ask her to open the closet to grab something for you. When she opens the door, jump out. She’ll be terrified and completely confused! Of course, this works best if she’s willing to help you.

Put red food coloring on her toothbrush or soap. Drop a few drops of red food coloring on her toothbrush or under the soap she uses, and she’ll think her mouth or hands are bleeding! While the food coloring is harmless, it will make her panic a bit before she realizes the truth. Just make sure your parents aren’t the first to use that soap.

Change her desktop background to a scary image. If your sister is old enough to use a computer, wait for her to leave the room or go to the bathroom. Then, change her desktop background to a creepy image for a little surprise when she returns. You can also use this trick with her phone's wallpaper, if you can sneakily access it.

Use a fake spider. A fake spider with a long, clear string or fishing line is a great tool for this prank. Stand away from your sister and use a stick to lift the spider. As she walks by, lower the string and make the spider fall next to her or even land on her. She’ll scream uncontrollably because this will come as a complete surprise.

Jump out from behind bushes. Who says pranks need to be complicated? Keeping things simple will work to your advantage. Just hide behind a bush in a place you know your sister will pass by, then jump out and yell. She’ll definitely scream because it’s not something that happens often when she’s walking through that area. If you want to go all out, you can wear a mask or a costume.

Tickle the back of her neck with a feather. This is a simple but effective prank. You just need a feather and to sneak up behind her. When you’re sure she’s focused on something else, use the feather to tickle the back of her neck. Apply just enough pressure for her to feel something, but not too much for her to immediately know it’s you. This will quickly make her scream and look around. If possible, hide or move away when she turns around so she won’t realize it’s you playing the prank.

Place a fake snake on her bed. Fake snakes can scare your sister at any age. Make sure her bed is neatly arranged, or at least that the blanket is folded neatly. Then, place a large fake snake on her pillow or under the blanket. Ensure that she won’t notice it when she looks at the bed. When she’s ready to go to bed and pulls the blanket back, she’ll scream loud enough for everyone in the house to hear.

Become a monster hiding under her bed. If your sister is still afraid of monsters lurking under the bed, you can turn that fear into reality. Sneak under her bed when she’s lying down or when you know she’s about to wake up. Then, when she gets out of bed, yawns, and prepares to start her day, reach out and grab her ankle. The scream you’ll hear will be priceless. It’ll be even more terrifying if you manage to make your hand feel cold and clammy when you do this.

Scare her in the mirror. If your sister loves spending hours looking at herself in the mirror, this is the perfect opportunity to frighten her. All you need to do is wear a creepy mask, smear some fake blood on your face, or do anything that makes your appearance look terrifying, then quietly sneak up behind her so she doesn’t notice. In no time, she’ll see your horrifying reflection in the mirror and scream in terror!

Frighten her while she’s sleeping. Once your sister is sound asleep, find something big and scary to place on her bed. You could use a bloody fake head, a large snake or lizard, a big spider, or any object you know will terrify her. Place these things on her bed so that when she wakes up, the first thing she sees is these terrifying items. This will surely make her scream in fear!
