The details
Build exciting marble racing courses with the PicassoTiles PTG100 100-piece Magnetic Tile Marble Run Building Set. The set includes 34 magnetic square track tiles, additional square and triangle tiles, nonmagnetic straight and curved tracks, U-turns, slopes, spiral funnels, supporting columns, and 5 steel-weighted marbles. Magnetic tiles form the supporting structure, while snap-together track components create pathways for marbles to travel through.
Designed for ages 3+, PTG100 encourages children to build towers, tunnels, drops, and multi-level marble runs. The click connections hold track sections together while allowing builders to change routes and experiment with different layouts. Through building, testing, and rebuilding, children can explore gravity, movement, spatial reasoning, and problem-solving during independent or shared STEM play.
5 Key Benefits
Create a Complete 100-Piece Marble Run
: Build custom racing courses with magnetic support tiles, nonmagnetic tracks, curved turns, slopes, spiral funnels, supporting columns, and 5 steel-weighted marbles.
Connect Tracks with Added Stability
: Use magnetic tiles to support the structure while snap-together track pieces create connected pathways that can be adjusted and rebuilt.
Design Exciting Multi-Level Courses
: Combine towers, tunnels, curved drops, U-turns, and spiral funnels to create winding routes with different heights and directions.
Race and Test 5 Steel-Weighted Marbles
: Release marbles through custom tracks, compare different pathways, and discover how changes in the layout affect their movement.
Explore STEM Through Moving Marbles
: Experiment with gravity, motion, sequencing, and structural balance while planning routes, identifying connection problems, and improving designs.
