E-Blox Crayola translucent bricks allow kids to construct 3D sculptures that illuminate with flashing lights triggered by sound and music. The set includes a sound-activated LED base plate with red, green, and blue lights that synchronize with detected audio for interactive play. Designed to support STEM learning, the bricks promote creativity, spatial reasoning, and problem-solving as children build structures on the sensor-equipped light plate. The 25 large translucent bricks easily assemble onto the included battery-powered base and are compatible with LEGO DUPLO-sized blocks for expanded building options. The set comes with a battery pack and sound sensor plate (requires 3 AA batteries, not included). Suitable for ages 5 and up, this set is ideal for creative play and hands-on learning.
