Enrich your child's mind with this exclusive Discovery Channel Microscope! View everything from butterfly wings to plant cell walls with this tool designed exclusively for The Discovery Channel. Micro and Macro settings let you explore objects from 40 to 400 times their actual size, with super clear images at every level. Constructed of a pivoting die-cast metal base, high-impact plastic, soft textured handgrips and a flexible, 360-degree rotating eyepiece, the 4-pound microscope ensures maximum stability and comfort for every viewing situation. All lenses are made of precision ground metal with optical quality glass and are designed to be interchangeable with most standard research quality microscopes. Two easy-to-replace lens bulbs create the microscope's independent light source, which focus's a light beam on (or through) the specimen in a clear, white viewing light.
