Some I haven't seen on here
Didn't read all these, but I didn't see many of the ones I know, so forgive me if this is redundant, I narrowed this down from a huge list, these are very very cool:
SUPERMAN: two people face each other, one getting ready to jump as high as possible (WATCH CEILING HEIGHT PLZ, good god, I saw someone's head smashed doing this before, your judgement is impaired so check BEFOREHAND) the 2 ppl hold hands on count of three the jumper jumps as high as he can while the other person pulls them up during 'liftoff' causing an extra boost. If your pretty faded, you'll feel as if you're flying.
ROLLERHUG: Hug someone HARD and count aloud together to twenty, focusing on tensing every little and large muscle on your torso, then letgo and relax...you should get a numb shock and spidery tingle after.
if you have access to sheepskin pelt.....holy god, run it all over, better than any massage, I have a quad pelt, 4 sewn together, you can envelope two people in this and its just awesome
visualization programs for winamp or equivalent...they react to music, very cool to watch. I recommend acidspunk gueiss and milkdrop...hook up to bigscreen is best
STROBE SHOWER: put the strobe light on lowest/slowest ping setting in bathroom WHERE IT WONT FALL IN WATER and take a shower, most lights are strong enough to blink through the shower curtain enough. The water droplets seem to freeze, you can't see them moving. Its also fun to make facial expressions if showering with bf/gf and move around while the strobe is on, a barrage of odd faces appear in your vision yet you cannot see the person in the act of moving from one position to the other.
Instead of giving a piggyback ride, give a camel right, have 2 people facing away from each other lock arms and one bends over, lifting the other over their bent spine (the camel) and another person lifts the one person's legs so they do not arch their back too far or have restricted breathing. Very weird.
Stare into a long tube-styled blacklight bulb that is on for about 30 secs, dont do it too close, it will work from farther away better. 5 ft or so is good. Look at peoples faces after, a negative of the bulb is burned into your retinas for a few seconds, and your brain will try to piece this together and if you are messed up enough, it will make wire frames and it looks like everyone is wearing pink sunglasses.
If you have a large mirror in your bathroom, collect one friend and stand in the bathroom light with as much room as you can get between the two of you both facing the mirror and being completely still for 30 secs or longer. The person by the switch quickly flips lights off, again the image of the two of you will be temp burned in your vision, and the person by the light moves quickly and quietly around to the opposite side of the other person and taps them on the shoulder. This works best if you don't tell them what you are doing, just tell them no matter what to keep looking at the same part of the mirror. Be prepared, this usually freaks people out pretty bad, if they are wasted they forget the light is off as they can still "see" you standing where you werem when the "ghost" taps their shoulder where you could not reach from your origianl position. This trick is easy to screw up when you're trashed, if its not done right, there are no effects at all.
TEMPLE RUB: places two or three primary fingers on the temples of another person and carefully jigle them as fast and gently as possible. If the person smokes beforehand this can lead to hammervision fairly easily.
I don't like eating ANYTHING on x, barely can stand gum, but place some FRESH pineapple slices in the freezer til they are very very cold or even frozen....the taste is incredible, its cold and fresh and you can spit the food out if you don't want it. Its the only thing I'll eat while rolling.
FALL INTO THE FLOOR: have one person lay on the floor face down arms above their head like diving into a pool with hands clasped, relaxing everything except elbows, which it is important to lock and KEEP LOCKED. Another person straddles the body, facing the same way, remaining standing. Lift the floor person by the clasped hands, you may need to remind them to lock elbows - people tend to relax them. Raise them up until you are stretching them, arching their back, be careful to give them time to tell you if you went to far to avoid injury and obviously don't do this to anyone with ANY kind of torso or back injuries. Lower them very slowly. I did this trick about 5 times and nothing happened, I thought it was lame as hell - then the last time I would have ever tried it, it worked! You feel like you should hit the floor way before you do, so you feel as if you are sinking into the floor, this can be kinda creepy if you are not in the right state of mind. I'm pretty skeptical about roll tricks, I think most of them are pretty stupid, but this one is very cool. If you didn't feel like you are falling, either you didn't do it right, or you are not rolling hard enough. This works, its pretty cool, and everyone should try it in a safe setting at least a few times if you don't get the feeling the first few.
PASS OUT: self explanatory, if you don't know how to do this DON't TRY IT. Don't let someone experiment on you, you could hurt yourself or them. If you know how, do it and try to have someone makes faces/throw some sticks, or make weird comments or noises as you awaken. Your brain 'resets' and you are very open to your environment as you do not know who you are or where you are upon awakening. This is NOT for people who tend to freak out, it will make them lose it for sure.
Microwave a hot towel and place over your face. I suggest microwaving while you are sober so you know how long to do it for just in case. Very soothing...if I was a guy, I would so get a straight razor shave just for this experience.
If you are into oils at all....eucalyptus oil drop in your hands and cup over nose/mouth. Inhale deeply, kinda avicks effect but if you're like me vicks can be nasty and mess with your stomach over the night. This is refreshing and shouldn't make you sick at all.
Oh and lots of hippy crack.
