Build it, launch it, watch it roll

This magnetic marble run turns playtime into hands-on science for children aged three and up. Kids snap together tiles, slopes, funnels and U-turns to build gravity-powered mazes, then send the steel marbles racing through. Along the way they practise problem-solving, spatial reasoning, hand-eye coordination and fine motor skills. The tiles are standard sized, so they combine with other magnetic tile sets for even bigger creations.

Why you'll love it

STEM play: build mazes and learn how gravity works
Magnetic tiles: snap together quickly and securely
Steel marbles: five included in the 100-piece set
Expandable: standard sizing fits other magnetic tile sets
Safety tested: BPA-free, non-toxic and lead-free materials

Perfect for: Christmas presents, rainy days, preschool play and classrooms
