Spring your marble to the track above with the “GraviTrax Jumper” and keep the action hopping!
Add the cool “GraviTrax Jumper” to your marble run track and get your marbles jumping! When your marble hits the “Jumper” switch, the platform is quickly raised one level and tips the marble on its way. Meanwhile, the raised platform creates a path directly below for a trailing marble to continue its journey — a cool way to split marbles onto different tracks! It’s a snap to combine this accessory with any “GraviTrax Starter-Set” to experience the power of gravity and educational fun today!
What makes a great toy? GraviTrax checks all the boxes! It’s a creative, modular, expandable track system that challenges children to use their imagination to design and build their own marble runs! Electronic-free, GraviTrax construction sets use STEM-friendly concepts while building critical thinking and problem-solving skills. Completely open-ended, every GraviTrax set has a boredom-busting variety of play options for hours of fascinating fun. Once the basics are mastered, simply add expansion sets and accessories to propel those metal marbles around the tricked-out track of your dreams!
Comes complete with 1 Jumper action tile, 1 long track, 2 medium tracks, 3 short tracks and instructions.
Lasting durability for girls and boys ages 8 and up, it’s the learning toy children (and savvy adults) return to over and over again!

Preislich völlig ok. Scheint stabil zu sein. Der Einbau erfordert ein bisschen Geschick. Es macht Sinn wenn man schon ein etwas größeres Gravitrax-Set hat, damit sich auch was mit dem Jumper entwickeln lässt.

Un juego útil, creativo y entretenido. Con la ventaja de que puedes irle regalando poco a poco ampliaciones como esta. Muy recomendable.

This game is extremely fun and truly teaches a child or an adult to understand how Gravity affects the steel ball bearings and how bridges work! It also teaches a child how to follow instructions and ultimately, their own imagination. I’m a senior and my grandson is 11. I recommend purchasing the large starter kit first, then decide on these extensions.

My son had the jumper for not even 12 hours and it won't work right already. When the marble is rolling down the track, the shacking of the track triggers the release on the jump mechanize, and it jump to soon. This looks like a design flaw. It could probably be redesigned to work but the way it is make now it won't work right will be sending it back.

This product is awesome. Probably the best toy my kids have; its a but addictive though and you constantly have to buy extension sets.

Worked great out of the box, however after using it a dozen times or so it had a hard time staying in the down position as the latch wouldn't catch. I used a knive to give it a "lip" to hold on to and that seemed to help. The Gravitrax Scoop does the same thing..........but much better and works every time. I would recommend getting that instead.
