If a marble goes to fast on the O-shaped tracks it would go to the other side and can go back to it and go in the hole.

So lucky! How did you get that deal with them? I wish I got free Gravitrax lol that stuff is expensive, not saying I think they should give me it or I want a business deal tho haha, I will still def buy their stuff. Just wondering how you got it. Also very nice video!

Before I started this channel, I reached out to a couple companies to see if they wanted to send products. My main channel, Race Grooves, had over 600,000 subscribers at the time and I had proven that I could grow an audience and attract eyeballs =)

Ho provato anch'io questo set tunnels con i binari Bernoulli e devo dire che per usarli hanno bisogno di molti blocchi verticali, soprattutto quelli con il buco, se hai blocchi in più allora va bene, ma se hai uno starter set insomma, non è l ideale, perché hanno bisogno di molta altezza per funzionare. Comunque è una sfida con la gravità e un buon allenamento per la mente.

I expected to get the expansion at my next birthday (6 nov 2025), but i got it for Christmas (25 dec 2024) 😆 🤣 😂 😆

Wow

[@universalightoflove]

That kind of track is called an O-rail

[@JDSuperstar11]

It’s fine It takes more times They almost rhyme I also almost made a triple rhyme

[@Sidecar_2025]

You did a quad rhyme!

[@maryemalkhafaji4424]

Sheesh

[@Gravitraxer_AangCZ]

How to use the 'O' rail? Looks like this ⬇️ ====0====

[@ignaziomonti5416]

I think the same..

[@GravitraxyBulgarianGuy]

If it's fast enough, it'll go trough the hole. But, if it's slow enough, it'll fall through the hole. There's 2 O-tracks - one pointing up and one pointing down.
