I gave up on pumps entirely. Instead, buy plastic quart containers and
lids from Home Depot (about $0.89) fill 1/3 to 1/4 way up with paint,
insert spoon, model getting paint on "palatte" of styrofoam plate--which
kids have to cover with plastic wrap at end of lesson for next day's paint.
I have used paint through four classes of 8th graders this way--and no
paint is polluted, non wasted.
