Send marbles through more twists and turns with the PicassoTiles Multicolor Curved Tube Marble Run Expansion Pack. This 8pc Pick-A-Part accessory set includes translucent curved tube tracks in pink, red, purple, and yellow for creating winding tunnels, smooth ramps, and extended pathways.

Each track measures approximately 2.17 x 5.91 inches and uses connector pegs to join compatible marble-run components. Designed to pair with full-sized PicassoTiles Marble Run and Magnetic Building sets, these add-on pieces give children more ways to expand existing layouts. Connecting, sequencing, testing, and repositioning the tracks encourages creativity, spatial reasoning, problem-solving, fine motor control, and hand-eye coordination through screen-free STEM play for ages 3+.

This product is an accessory expansion for compatible full-sized PicassoTiles Marble Run and Magnetic Building sets. A complete base set, magnetic tiles, marbles, and other track components are not listed as included.

Children can incorporate the 8 curved tube tracks into a compatible full-sized PicassoTiles Marble Run or Magnetic Building set. The translucent pieces add colorful pathways that can become winding tunnels, gradual ramps, or extended sections within an existing marble-run design.

Creating a working route encourages children to consider direction, sequence, height, connection points, and the path a marble will follow. Attaching and arranging the tracks supports fine motor control and hand-eye coordination while helping builders explore spatial relationships, motion, gravity, and cause and effect.

After assembling a pathway, children can release a marble, observe its movement, and identify areas that need adjustment. Changing the track position, slope, or sequence introduces an engaging cycle of planning, testing, evaluating, and rebuilding that encourages curiosity, persistence, and creative STEM problem-solving.
