Looking to wow your friends at your next big sleepover? We have some slumber party tricks that definitely will have your pals going, “ooh” and “aah.” You are getting sleepy now -- yeah, right!

Mind Over Matter
Do you know your thoughts can create pure energy? Demonstrate this wondrous fact to your party guests by swinging a charm necklace around ... with your mind!

Hold the necklace at the clasp with your thumb and index finger so it’s hanging straight down. Steadying your elbow on a table, hold perfectly still and tell the chain to swing clockwise. Or back and forth. Now tell it to reverse directions, then to stop. Let your friends try it. (If you establish that clockwise stands for “yes” and counterclockwise mean “no,” you can use this as a sort of lie detector during your game of Truth or Dare!)

Bending Toothbrushes
Hand out brand-new toothbrushes (go for sparkly ones or those with cartoon characters) as party favors ... but these aren’t for brushing. Instead, turn ’em into bracelets!

Here’s how: Use tweezers or pliers to pluck the bristles out of each brush. Boil a large pot of water, and drop the toothbrushes in for about five minutes. Have a parent use tongs to remove each one. Careful, they’re hot! Use oven mitts to bend them so they fit inside a large coffee mug. Pour cold water in the mug to cool them. When they’re done, you’ll have a cool cuff bracelet.

Light as a Feather
No one is quite sure why this works, but it does -- and it has for generations. In fact, your mother and grandmother probably did this trick at their slumber parties back in the day.

Have one guest sit on a chair, facing west or north, with her hands in her lap and feet flat on the floor. Have four other girls, two on each side, stand beside the chair. Place your hand, palm down, on top of the sitter’s head, and then have the other girls stack their hands on top of yours. Count to 10 before quickly removing your hands from her head and placing two fingers under her knees and two fingers under her armpits -- and lift her up! Slowly lower her back to the chair. Amazing, right?

Quantum Pajama Leap
While your friends are all in the kitchen making toothbrush bracelets, send someone to the party room to scramble everybody’s pajamas. Take them all out of their overnight bags, and place them in someone else’s. When it’s time for your girls to slip into their PJs, they’ll be all ... huh?

Yeah, boys can be baffling. That’s why this quiz is designed to help you figure out if you’re picking up on his signals. Hopefully, it’ll clear up some of the confusion about what’s going on in his head so you’re not scratching yours and going, “Huh!?!”

Nobody’s perfect. In fact, you’re fine exactly the way you are! But everybody has room for improvement -- it’s a never-ending journey. Take this quiz to find out if you’re giving it your all ... or not so much.

Being single on Valentine’s Day can make a girl a little green with envy when her coupled-up friends keep talking about how psyched they are for the big day. But we’ve got suggestions for awesome V-Day plans that are so crazy-fun that they might make your taken friends jealous of you. Heck, the attached girls might even ditch their BFs so they can get in on the excitement!

Organize a Single-girl Swap
No need to feel left out when all the couples exchange heart-shaped gifts. Get a bunch of your single friends to draw names out of a hat for a present swap. Set a $5 price limit, then pick out cool prezzies, like costume jewelry or an artsy thrift-store vase.

Hold a Candy-tasting Bash
The fun in getting a box of chocolates is sampling all the different flavors. So invite a few of your besties over to your house and tell each guest to bring along her favorite confections. Then eat up!

Go on a Double Friend-date
Ask one of your single guy friends to grab dinner with you on V-Day, and have your BFF do the same. You can have fun scoping out all the couples at the restaurant and guessing which ones will actually last, based on how much fun each pair seems to be having.

Make up New Makeup
Create totally new lip colors without spending a cent. Just put a dime-size amount of lip gloss on the back of your hand, dip your finger in your favorite shade of eye shadow, and mix it in with the gloss. Even funky combos, like purple eye shadow with orange-y gloss, look really cool -- we’ve tried it! Bonus: This one’s just as fun with friends as it is solo.

Dance the Night Away
Dance, dance parties -- where you go into a dimly lit room with tons of girls and dance your butt off to the hottest new music -- are really trendy these days. Host your own by making a playlist full of upbeat tunes (we heart tracks by Lady Gaga, Katy Perry and Pink). Then have the girls over to get your dance on.

Create Your Own Candy Hearts
Conversation heart candies are a must on Valentine’s Day. Messages like “Tweet Me” are cute and all, but we know you can come up with something way better. Pick up a pack of the candies and a food-decorating pen (available at baking supply stores), then write your own phrases on the blank side of each candy. Your ladies will love getting personalized messages instead of the played-out premade ones!

At some time or another, you’ll surely have to deal with the discomfort of “the friendship triangle.” Put three girls together and, well, it almost always spells triple t-r-o-u-b-l-e! Here, we take a brutally honest look at this friendship dynamic.

You’re the odd girl out
You’re the one being excluded? Bummer. It never feels good when you think you’re gonna have a good time with the girls and then find yourself tossed aside like a spare wheel. So ya know what? It’s this simple: Remove yourself from the situation. Call a parent to pick you up, go to another room, put on your ear buds -- whatever you’ve gotta do to ignore these meanies.

You’re not having fun, right? So why stick around and endure any more of their bad behavior? You could try to hang out with these two again another time, but if they continue to treat you like an outsider, it’s time to ice them out until they’re ready to play nice (if they ever are!).

You’re the instigator
OK, be honest: Are you the leader in this three-ring circus? Are you influencing one friend to oust the other? If so, stop that right now. Fact is you might think you’re in charge, but you’re actually completely out of control because you don’t even recognize what’s really going on -- which is that you are jealous.

Yep, we said it. You feel threatened, and so you’re turning your insecurities around on someone else. But you’d better rethink your actions. You see, the thing about friendship triangles is that they’re ever-shifting. It could all change tomorrow when it’s your turn to be the odd girl out (see above).

You’re stuck in the middle
So you’re good friends with both of these girls, but they’re just not hitting it off. First of all, do not let the instigator (above) influence you into ganging up on your other friend. It’s just wrong. You chose to be friends with both girls, so don’t be put in a position where you’re expected to pick sides.

Look, it is not your job to be the mediator -- so don’t even try. If these two refuse to get along, the advice here is similar to that we gave for the odd girl out: Walk away. Then hang out with Friend A and Friend B on separate days -- and refuse to get sucked into their drama!
