What are some pranks I can play with pens?

You can play a prank with pens by putting several drops of vegetable oil on the cap of the pen. Then, twist the cap and suddenly remove it while someone is writing. The person will be surprised when their writing starts to smear and blot. Alternatively, you could take a permanent black marker pen and switch it with a regular felt-tip or ballpoint pen. People might complain when they find out their writing isn't as bold as usual! Another idea is to take multiple felt-tip or ballpoint pens, write "2B" on each one, then place them in such a way that when seen from one end it appears as if one large "2B" was written. When people read what is written from afar, they will be puzzled since no single pen can write so big!

You can play pranks with pens by using a felt tip pen to draw on the person's skin, making sure to get them to feel it afterwards; filling a plastic tube or balloon with pens and surprise the person when they pop it; writing messages or drawings on random surfaces like in public restrooms or as graffiti; creating "pens that move" by putting two regular pens side by side and then sticking them together using glue - now when one is moved the other will follow; taking disposable ballpoint pens apart and putting them back together so that only part of the cap screws onto the body of the pen - when someone grabs it they won't be able to get their fingers back in without twisting off half of it.
