Sharp
as a marble
as a bag of rocks
as a bowling ball

Few
peas shy of a casserole
keys of a keyboard
cards of a deck
screws of a toolbox

sandwiches of a picnic
threads of a sweater
two bricks of a load
one twist of a slinky

roots of an apple tree
couple shakes of a sauce bottle
people of a party
pinky of a hand

leaves of a bush
springs of a watch.
bales short of a wagon load.
needles short of a sewing kit
bits of a byte

slice of a loaf
megabytes of a gig
electrons of an isotope
grapes of a fruit salad

feathers of a duck
whisker of a kitten
olive of a martini
carrots of a carrot cake
tuppence of a bob
atoms of critical mass

big bang of a universe
ooze of life on earth
sperm of a baby

almost there.
