Squirt some of this disappearing ink onto a friend or co-workers white shirt or pants- and wait for the ruckus to begin! The disappearing ink comes in a one ounce quirt bottle- and the ink comes out very dark blue- but disappears completely within minutes. Great fun and a classic prank!****Features:*** Holds 1oz quirt bottle of disappearing liquid*** Ink comes out very dark blue- but disappears completely within minutes
