$9.99 /

Create compact turns and colorful tunnels with the PicassoTiles Multicolor Short Curved Tube Marble Run Expansion Pack. This 12pc Pick-A-Part accessory set includes translucent short curved tube tracks for adding tighter pathways, quick direction changes, and new route possibilities to existing builds.

Each track measures approximately 2.17 x 2.95 inches and features connector pegs for attaching to compatible marble-run components. Designed to pair with full-sized PicassoTiles Marble Run and Magnetic Building sets, the pieces help children expand layouts without purchasing another complete set. 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+.

5 Key Benefits

  1. Create Compact Turns: Short curved tube tracks add tighter turns, tunnels, and pathway changes to compatible marble-run layouts.
  2. Expand Existing Builds: Add 12 connector-track pieces to full-sized PicassoTiles sets for more detailed routes and structures.
  3. Build with Color: The translucent multicolor assortment brings visual variety to every new marble-run configuration.
  4. Explore STEM Through Motion: Planning routes and observing marble movement encourage sequencing, spatial reasoning, and problem-solving.
  5. Test and Rebuild: Reconfigurable tracks let children adjust their designs and explore different solutions repeatedly.

This accessory pack is designed to expand 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 add the 12 short curved tube tracks to a compatible full-sized PicassoTiles Marble Run or Magnetic Building set. Their compact size makes them useful for introducing tighter turns, short tunnels, and quick direction changes within an existing pathway.

Building a working route encourages children to consider connection points, sequence, direction, height, and the path a marble will follow. Attaching and repositioning the pieces supports fine motor control and hand-eye coordination while introducing early concepts involving motion, gravity, spatial relationships, and cause and effect.

After constructing a route, children can release a marble, observe its movement, and adjust any section that interrupts the pathway. Repeating this process of planning, building, testing, and redesigning encourages curiosity, persistence, creative problem-solving, and hands-on STEM exploration.
