Exploding pens are a type of novelty item designed to create a surprising effect when used. Typically, they contain a small mechanism that releases a pop or a burst of confetti when the pen is clicked or pressed. These pens are often used as gag gifts or party favors, adding an element of fun to writing. While the concept of exploding pens is entertaining, they are not practical for everyday use. They can be found in various shapes and colors, often marketed towards children or for use in pranks. However, they should be handled with care to avoid any unintended mess or injury.
