Prank Advice for New Year!!!

Ok first of all I m a dude don t know why my phone says I m this girl. Probably because she went on Facebook with my phone some time ago.

Anyway I wanted some advice on pranking some girls we re spending new year s eve with. We re 10 boys 8 girls. We ll stay in a house in the countryside . We ll stay there 3 nights.We re all friends since a long time. Some of these girls I m sorry to say are not geniuses.

Now i want some advice on what pranks do to them and how.

Some ideas i had were to bring some fake cocaine or maybe stage a fake suicide, but for this last one I have no clue on how to do that. Maybe we could fake a couple of us are gay and try to keep it a secret, maybe that there s a serial killer hidden in the forest nearby?

The kind of prank I want to do is one that makes them freak out or be scared or awkward. Not looking for the kind of joke that leaves them wet or dirty and angry.

Please be detailed on the "how to" part
