Marbles and magnetism join forces to teach physics and engineering concepts in National Geographic’s Magnetic Marble Run construction sets.
Geared for children ages 8 and up, the constructions are offered in two sizes: small (50 pieces) and large (90 pieces). Each set provides a mixture of tracks, snap-fit connectors, trick pieces, and marbles that can be combined into Rube Goldberg-style racetracks.
The magnetic pieces allow for vertical track building on either the included magnet board or any magnetic surface, like a refrigerator or locker. To encourage creativity and learning, each construction set comes with a marble run guide with track-building puzzles and challenges; and, a learning guide focused on various scientific concepts the toy demonstrates.
The sets can be purchased from Nat Geo’s Amazon store. The smaller size checks in at $39.99 USD and the large at $69.99 USD.
