pens
 
 

 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.
