Here are some pranks you can play with pens: 

1. Stash pens in places and set a timer to watch people try to find them.
2. Give a friend a pen filled with ink and tell them it’s an ordinary pen - but make sure they use it!
3. Put a pen into a sugar cube and place it where someone is sure to see it – watch them try to figure out why it isn’t dissolving.
4. Change the tip of your friend’s pen over to a highlighter for them – when they least expect it! 
5. Hide tiny pens around the house or office, challenge your friends to a pen-gathering scavenger hunt. 
6. When you receive an unexpected gift, secretly swap it for one you know your friend will love - and hide the original in the box for them to find. 
7. Give people an ordinary pen, but color-code the ink, so each color represents a different emotion – watch them try to interpret what you’ve written! 
8. Use a special pen to draw in the sky at night so that others can find the artwork when they wake up. 
9. In a group situation, have everyone write down something secret and hidden on a piece of paper, put them in the same pen, and have a winner chosen via guessing.
