pranks!!! give me some people please!!!

Handcuff her to a piece of equipment A somewhat costly, but fun prank would be to totally saran wrap her shut

This is my favorite prank and it's a great revenge but still harmless. Okay, so get a bottle of coke (preferably diet coke if she drinks it). Get a piece of Mentos and put a string through it with a hammer or just glue or tape the string. Stick the mentos on top of the cap and close the bottle with the string hanging out (cut the string afterward) so that the mentos would fall in when opened. Yea, when mentos mix with coke, it sort of blows up. Pranks could be great as long as no one gets hurt Keep it fun

Get one of those little funnels you use to pour sugar in a drink, a quarter and a bottle of water. Tell her you have a game for her to play and want to see if she can do it. Put the funnel in the top of your pants and place the quarter on your forehead. Tell her the object is to flip the quarter into the funnel. Do it a few times and just miss tell her it's really hard and you bet her a thousand bucks she can't do it. Well when it's her turn as soon as she puts the quarter on her forehead pour your ice cold bottle of water down the funnel. It works every time. Have fun! And don't forget to run after she's realized what you did!
