RavensburgerGraviTrax: Trampoline Accessory | Marble Run & STEM Toy for Boys & Girls Ages 8 & Up | Accessory for 2019 Toy of The Year Finalist

Great toy. It does make the trampoline effect with the marble.

Bought this for my son’s birthday. He already had this one a couple of years ago. He didn’t know he can add duplicates to his current set. Now he wants an abundance oh this 🤣.

It works perfectly. And just so you know it comes with two larger marbles for the weighted end.

Work pretty well. You need to experiment with it to get the right height. Kids can easily stretch the netting if not supervised.

It's a lot more predictable than I expected. My nephew really wanted it. I thought we'd be fetching his marbles from under the couch, but it's actually 100% predictable when paired with the scoop accessory. And the kid loves it. It's more of a flashy fun whimsical piece, not terribly functional in terms of building a fast track. But don't be scared by the low rating. It's an easy component to integrate, surprisingly. It's not crap.

The trampoline has become one of my son's favorite accessories to his Gravitrax set. He was frustrated with it for the first day, trying to figure out how to make it work, but since then, has come up with numerous applications and have since bought two additional trampoline packs. The scoop into the trampoline is probably one of his favorites. Our household loves Gravitrax!

We are not sure if we did it correctly but the marbles don’t bounce on the trampoline as we’d expected it to. We tired many different ways but didn’t have any luck with it.
