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

Such as:
BIG GIANT HEAD
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.)

COLA CAN BEATBOX
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.)

LIVING WITH AN ECHO
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.
DAMN!
UH-uh. TIC-tic. TUH-tuh. TES-tes.
NEPTUNE'S HAMMER
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.
