Marble runs are one of those classic toys that are instantly recognizeable across the span of generations; grandparents, parents, and kids alike can all recall playing with some variation on the theme, whether we're talking bulky but classic wooden building pieces with half-moon tracks, colorful lightweight plastic tubing with charming windmills and steep drops, or even mechanical versions featuring lift chains and conveyor belts.  But no matter which style you're familiar with, we can guarantee that, whether you're young, old, or in-between, you've NEVER seen a marble run quite like this!

Introducing the incredible Gravitrax Marble Run, an innovative construction set with endless building possibilities, STEM compatibility, and even an unprecedented VR experience that allows you to viscerally experience your complex and exciting creations!  Using futuristic translucent hexagon base pieces, you'll plan the structure of your coaster, creating elevated platforms (you'll receive two of these transparent platforms) by stacking smaller hexagonal height tiles (52 included).  You'll have to plan carefully however, because the success of your coaster depends on your ability to harness gravity and kinetic energy effectively; if you don't build a high base section, you won't have the momentum you need to complete the run.  However, once you've got a solid foundation built, the fun can truly begin.

Once you stacked your foundations, use the hexagonal turning pieces to plan your pivots and guide the marbles along the tracks, which bridge the gaps between your base structures.  Cause the 6 included marbles to fly through space along the rails to the next section, hurtling down steep drops and back up again into hairpin turns.  But that's not all!  You'll also receive a sampling of sophisticated special tiles that allow you to spice up your ride.  These special tiles set Gravitrax apart from any marble run before it.  The magnetic cannon gives the marble speed to help extend your run by boosting it up inclines and down tracks, the freefall piece will drop your marble many hexagonal stories down to a splash piece below, sending multiple marbles careening down different sections of track, and the vortex will dizzily spin your marbles about before flushing them down the center of the piece!  Use these special pieces to create a truly spectacular run unlike any other!

And finally, once you've used all your ingenuity, critical thinking, and physics skills the craft the perfect coaster, fetch your VR headset (the video can also be projected onto a tv with the right casting device), download the Gravitrax app, and ride your own coaster in the first person from the perspective of the marble!  Experience every twist, turn, drop, cannon shot, and freefall in realtime and get some firsthand knowledge on what it would feel like to ride your run like a roller coaster!  Gravitrax offers the first fully immersive marble run experience.  Grab the grandparents, aunts, uncles, the whole family, and experience the most incredible iteration of this classic learning toy together!
