Feeling a need to feel like a kid again, if only for a few minutes? Do this now!

Do the Celestial Crawl
On a cloudless warm night, walk around until you can put a nearby building or tree very close to a bright star in the eastern sky. Now lay on the ground and move yourself until the corner of the building or the top of the tree just BARELY covers that star. Wait a moment. The star will reappear. Wiggle along to cover up the star again. It reappears. Keep wiggling along. (Um… notice that the entire Earth is rotating beneath you?)
Yawn. (no, REALLY yawn), then immediately curl your tongue backwards and force it against the roof of your mouth. The saliva glands under your tongue will squirt like a squirtgun! You can only squirt once or twice before another yawn is required. Also works while eating (or sucking on hard candy.) Practice this in front of a mirror until you can slightly part your lips and silently hit a target with deadly accuracy. Hey! Is it raining in here?
Burst of flavor
While reading, eat something. Notice that the flavor vanishes as soon as you get involved with the story you’re reading? Now concentrate on your mouth, and the flavor explodes into reality. By concentrating on the text or on your mouth, you can make the flavor flash on and off. WEIRD!
Finger of PAIN
After getting out of the car, quickly touch one of your passengers. Snap! Why waste a good “zap” on the car door? (If you don’t enjoy sparks, then use the car keys to touch your passenger. The shock still occurs, but YOU won’t feel it!)
Visible Touch
Look to the left, close your eyes, then touch the rightmost edge of your right eyeball with a fingertip. (Push gently on your eyelid, don’t touch the eye itself!) Wiggle your finger up and down. See anything off to the left? That’s the “image” of your fingertip, but the retina of your eye is feeling it, not seeing it. Move your finger UP, and the black/silver splotch moves DOWN. Use two fingertips, and you see two splotches. This is the realm where touching meets seeing.
Restaurant Super-candle
…with a foot-high flame. While in a restaurant, tear off a bit of a napkin or other paper, and twiddle it into a little rod the thickness of a pencil lead. Dip both ends into the liquid candle wax so the whole thing is wetted, then wait for it to harden (or chill it in your drink.) Carefully jab this hard wax rod into the top of the candle so it becomes a second wick. Tilt the candle to expose this extra wick to flame. Now REPEAT THE PROCESS! Five wicks create a tall flame like a blow torch which makes a soft roaring noise.
Tube of Boob
Tune your TV to a blank station and adjust it for good “snow”. Stare into the snow. Imagine the number “3”, and it will appear as a 3-shaped flickering. But then it will start to slowly rotate. Mentally erase the 3, then imagine a horizontal line. It appears, but it won’t stay still, it wants to drift and rotate. Make it shrink and vanish. Keep staring, and soon the snow will smoothly ripple, as if you were looking through the distorting water of complicated waves in a swimming pool. Think of more stuff to create. Who says that watching TV for hours isn’t worthwhile?!
