Backbencher: Spring Refill to Play During Boring Classes

Things that you need:
1. Empty Refill
2. Pencil Sharpner

Hold Refill oblique such that the side of tube facing sharpener should be upwards

Press the refill against the blade strongly and sharp just like you sharp a pencil.
Make sure that you continue to do it till you reach the end.
Do it Slowly and at the end just break the refill
And you are done to play with your spring refill during boring classes.
