Garden of delights
Keep a pocketful of dimes and quarters with you at all
times, and constantly leave them in knee-level weird places where
only a child would ever look. Inside the hollow shafts of
toilet-paper holders. Balanced along the ridges of decorative
molding. Inside pencil sharpeners at the local elementary school.
In the coin slots of gumball-dispensers (give 'em a half-turn.)
Imagine the eventual entertainment that will result.
my favourite from :
SCIENCE
HOBBYIST: Do This Now
nah, this is better :
Dry your tongue!
Get a clean cloth or paper towel. Stick out your tongue, then
dry it thoroughly with the cloth. Keep sticking it out so it will
dry a bit more. Now challenge your friends to feel your dry tongue
surface. Weird and creepy. Grab the hands of unsuspecting
passersby, and force them up against your warm dry tongue.
