Slowly Expanding Executive Pen

One of the ways in which we while away the winter hours in the lab is to place a few pieces of dry ice in a latex glove and then tie it shut. Over the next hour or so, the dry ice sublimes and the glove gradually expands to beach-ball dimensions. Eventually (if it has no pinhole leaks) it makes a satisfying bang.

MaxCo Office Brightening, Inc., is now proud to bring this harmless fun to the boardroom. The MaxCo Slowly Inflating Exective Pen looks like a classy fountain pen, but is actually a black latex balloon stretched over a cylindrical wire frame.

As you go into the meeting, simply unscrew the end of the SIEP and pop in a few pieces of dry ice before placing it nonchalently on the table. As you review the month's sales figures in Powerpoint, your SIEP will slowly expand to become a large pennish marrow, to the bewilderment and consternation of your colleagues.

NOTE: MaxCo Office Brightening, Inc., is a firm with Family Values. We actively discourage the use of double-entendres regarding slowly inflating cylinders.
