Boys and girls ages 8 and up can indulge their passion for science and space with this LEGO® Creator 3 in 1 Space Exploration Telescope (31378) building set. This detailed STEM toy offers 3 different building options with the same set of bricks. Kids can choose to build an adjustable telescope toy on a tripod with a solar system model featuring the sun and 7 planets that can be spun around. This can be rebuilt into an adjustable microscope toy or a UFO model with posable antennae and legs that flip out to display it. Each space toy includes a light brick (batteries included), which kids can activate by pushing a button to project images from the telescope onto a surface, illuminate images on the microscope or beam a light from underneath the UFO. There are 3 interchangeable decorated lenses, with images of a planet, a star and the Moon to project from the telescope or view inside the microscope. Please note models cannot be built simultaneously. Set contains 278 pieces.
