How can you make someone pass out?

hit yourself HARD with a brick.

first bend over so that ur knees reach ur chest, then breath as fast as u can for 10 seconds, then take in 1 deep breath and hold it while u stand up really fast, then take ur hands and place them on each side of ur treacia where u normally feel for ur pulse but on both sides push inwards and hold it, u'll be unconciouss in a few seconds. oh make sure u land on something soft cause ur more likely to fall backwards.

hope this helps.
