What pranks can you play on people when they sleep over?

wait till their asleep then put there middle finger (either hand, try their writing hand, it works the best) in a cup of warm water, then watch the magic. sometimes this prank doesn't always work but my friend did however wet himself. (make sure there not sleeping on your bed)

silly string! lots of silly string! spray it all over the person while there sleeping then use fake spiders and put them in the silly string. (be prepared for a big clean up day though)

If you have a bag of potato chips and green nail polish then this is a wonderful prank to pull(this works better on boys and brothers):

1.invite some friends over for a sleep over.

2.wait till its real late.

3.boys get hungry so they will want something to eat.

4.bring them a bag of potato chips and say in a warning voice, "if you guys eat these, your nails will turn green in the morning after you wake up".

5.they won't believe you and they'll dig in, make sure you don't eat any, instead have an apple or orange.

6.make sure it looks like you feel asleep first, then wait till the others have fallen asleep, go into the bathroom and wait 5-10 minutes then flush the toilet.

7.make sure while you made your trip you got the green nail polish.

8.go to your bed very quietly and pretend to go to sleep just in case someone woke up.

9.after awhile get up and get a flash light, make sure either you, your mom, or your sister is good at painting nails.

10. get them to paint your buddies nails and then go to sleep.

11.you might get an early wake up call from your friends as they shockingly take in there newly green nails.

12. laugh at them and say, "i told you so". they'll be owned and you'll have a good laugh ^.^ hope you have fun!

P.S. make sure that you later tell them is was only a prank and it can come off with nail polish remover.(if your doing this prank on your brother just make sure you did steps 4 and 5 wait till he's asleep and make your move, it works just as good)

Classic pranks are always the funniest (and the most forgivable). Put shaving cream on their hand, and tickle their nose with a fake feather. :) Happy Pranking!

Also in the night, you can take baby carrots and shove them up your friends noses. You can put their hand in hot water. You can spill water on their sleeping bags or beds so it looks like he/she drooled. Put makeup on them in the middle of the night. If it is the owner who slept earliest, you can pile his/her clothes like a wall so he/she cant move unless he/she knocks down ALL their clothings.
