Ball point pens is used quite often in school. They are used for
writhing, drawing, and notes. How do they work? That is a common question
I heat so hear you are.
The pen has as the name suggests has a ball in it it is the part that
you right with it rolls across your paper and it spinet draws ink
from the back of the pen where the tube of ink is it then stays on that
part pf the ball that just went through Th. ink. it puts the ink on the
paper and starts all over again. The ink then soaks in to the paper and
it stays. That is how a ball point pen works.
