What Makes this set WOW?

3-in-1 versatility: The set allows you to build a telescope on a tripod, a microscope or a UFO ship, which provides a variety of science and fantasy play scenarios.

Interactive Light Brick: Built-in backlight allows you to physically project images from a telescope onto a wall or highlight samples under a microscope.

Interchangeable Art Lenses: The set comes with three special tiles with planet, star and moon images that can be changed to create different light projections.

Movable micro-model of the solar system: The main telescope model includes a miniature model of the sun and seven planets that can be rotated around an axis.

Adjustable STEM Design: Both the telescope and microscope have movable joints to change the angle of inclination, teaching children the basics of using optical instruments.
