Description

This ink-credible 4.5-inch Disappearing Ink Pen Tube is full of a blue colored liquid that will vanish before your eyes! You'll have your friends and family asking, "Is it magic or is it science?". The secret is in the chemicals that make up the ink. When you write with or squeeze this fluid onto your demonstration, either a friend's t-shirt or school assignment, the chemicals in the blue ink react with carbon dioxide in the air as the liquid dries to make the color disappear. Great prank for April Fool's Day or magic show. Leaves no mark or stain. Avoid contact with eyes. Adult supervision required. 24 per box. 2 dozen minimum.
