After you put the puzzle together, turn off the lights and see a surprise as it glows in the dark! Puzzle Doubles! Glow-in-the-Dark puzzles are a fun way to expand your knowledge of different environments. Place all the puzzle pieces with the colored image side face up and have your child assemble the puzzle. Parental involvement may be needed depending upon the age of the child. Once assembled, the puzzle becomes a "talk about" puzzle, as there are many images in the scene to promote parent-child conversation. After the puzzle is assembled, the child can activate the glow-in-the-dark feature by placing the puzzle under a bright light. The brightest glow will come from a UV lamp (black light) or a fluorescent bulb. Turn out the lights and see what's "glowing" behind the scene! Additionally turn the puzzle over and you have a coloring activity.Details:Multicolor36" x 24" assembled sizeIncludes 100 glow-in-the-dark puzzle piecesFor 1 or more playersFor ages 3 and up
