Another "brain modification" trick

  1. I just added lots more, uh... "things."


    Childhood brain-modification techniques

    Such as:

    Get two identical cola cans or yogurt cups or bottles of white-out. Place them
    in front of you on the desk, a couple of inches apart horizontally, then rotate
    them so they look identical. Then cross your eyes so you see three of them.
    Concentrate on the middle one, and tilt your head a bit so it isn't doubled
    (maybe rotate one object until the middle one looks perfect.) The middle object
    looks perfectly 3D... but it's tiny! Actually, the angles of your eyes make
    them act farther apart than usual, as if your head was huge. OK, now carefully
    grasp the two objects and very slowly draw them apart while concentrating on
    the middle one. It will get smaller and smaller while staying exactly the same
    size. (Or your head will grow larger and larger.)

    Crush the sides of a coke can inwards, but only near the top, then rotate it
    90deg and crush the sides inwards near the bottom. Now push the top and bottom
    together (or stomp on it) and it easily collapses into a small round puck. Now
    pull it partway apart again and you'll hear all sorts of snaps and poings. Push
    it in and out and the sequence of poings will play forwards and back like a
    recording. It's a mechanical beatbox sequencer, a toy marimba, a percussion
    accordian. Make mouthsounds to accompany the noises (such as whistling while
    humming, or sucking lips to make swarms of mosquitoes.)

    Try speaking a simple sentence, but repeat each word twice. "Testing-testing
    one-one two-two three-three." It sounds a bit like a genuine echo. OK, now
    speak each individual syllable twice: "Tes-Tes Ting-Ting One-One Two-Two Three-
    Three." Say it a few times fast. That sounds very much like an echo. Finally,
    say it with the accent on the first of each syllables, with no pause between
    pairs but a slight pause between the different syllables. Speak with constant
    tone, not like conversation but like making an announcement at a ball game.
    "TES(tes,) TING(ting,) ONE(one,) TWO(two,) THREE(three). It echos! Sounds
    disturbingly real!







    Now practice until you can do it fast. Go find unattended microphones, and
    screw with the sound engineer's head. How to get rid of that dammned echo? Try
    different hookups. Is it still there? YEP-yep.
    UH-uh. TIC-tic. TUH-tuh. TES-tes.

    Obtain some V8 juice or orange juice in a small glass bottle. (Any vacuum-
    packed non-carbonated liquid should work.) Hold it in one hand and strike the
    top with the heel of your other hand. If you strike it hard, the glass bottom
    will fly off and the liquid will blast downwards. If you strike it more softly,
    you'll hear a loud "snap" sound. Practice striking it sofly enough to obtain
    the interesting noise. Now break the seal and let in the air, and you'll find
    that you can't create the snapping sound anymore. The sound is caused by
    cavitation, by a "water hammer" effect. Liquids are held together by atomic
    bonding, and if you create negative pressure, you can tear open some bubbles
    made of vacuum. When the bubbles slam shut again, the water pressure becomes
    momentarily immense. But if the liquid is at atmospheric pressure to begin, you
    can't create enough negative pressure to get to the cavitation realm. This
    works with canned vegetables too, and with glass jars of pasta sauce.

    You might want to ease off on the chemicals a bit...
  3. Try the cavitation demo above. I've also heard that it can blow the
    off a glass beer bottle, but haven't tried it.

    Another one, with less physics this time:

    At a restaurant with friends, give everyone the jitters by playing
    with a fork very close to your eyeball. Use the tines to pull your
    eyelid down, etc. Everyone is creeped out. Now take one of those tiny
    plastic cups of ultrapasturized creamer, cup it in your hand and hold
    it up to your eye without anyone noticing, use the fork to poke holes
    in the paper lid (looks like you're stabbing your eye,) then squeeze
    the cup and scream while dropping the fork! White gunk will squirt all
    over the table. (From PLAY WITH YOUR FOOD, by Penn and Teller.)

    Screaming is expected. You really wanna screw with their
    heads, just sigh and say, "Oh crap, not again."

    The facial expressions of cognitive dissonance are priceless.

  5. For some reason, this thread made me think of the "redneck vasectomy"

  6. Somehow I've missed that one, and I collect 'em (like
    Poles collect Polack jokes).

    Care to recount it? Please?

    How could anybody have white gunk in their eyeball? How would they see
    through it?

    People usually don't think things through to this depth when they're
    watching someone poke their eyeball out with a fork.
  9. Heh. The joke is obviously aimed at the general public, where white
    eyeballs must be full of white stuff.

    Now to scare medical personel, you'd have to first teach yourself to
    squirt fluids through that nasal/ocular duct which opens at the corner
    of your eye. Take a big gulp of water, hold your nose, then pretend
    to probe your eyeball with a fork. (SQUIRT) Oops! I hate it when
    that happens.
