Hi Gravitrax Fans! Today we're going to unbox the GraviTrax Tunnels Expansion Set.
The Tunnels Expansion Set requires that you already own a GraviTrax Starter Set to use.
GraviTrax is a modular marble run system from Ravensburger,
and I highly recommend this Tunnels Expansion Set for all the unique pieces that are inside.
First of all, you get a mini manual that tells you what the tunnel pieces are,
how to put them together, and how to use them in a track.
Next you have some of the basic tiles.
You get 2 of them with the two entrances and 6 of them with the three entrances, and what happens
is you put these tunnel inserts inside of those basic tiles. We'll show you how those go together.
So we'll start with the straight tunnel pieces. You get two straight tunnel pieces. The inserts
just go into the base tile like that, and I like using them like this without the tunnel top
a lot. But you can clip the tunnel top on. It just snaps in right like that. So there's two
of these in the set. Now the reason I like using them without the tunnel tops, is because the only
other straight piece, the only other straight tile in the GraviTrax universe is the junction, which,
sometimes marbles get hung up in junctions and go the wrong way,
whereas with these tunnel pieces they can't help but go straight through.
Then you have the curved tunnel pieces. There's four of those, and they go into the three entrance
basic tiles. So I'm just putting the inserts in. And then you have the curved tunnel piece
that goes on top, and just like with the straight piece, it just snaps in there.
There are four curved tunnel pieces in the Tunnel
Expansion Set. And these curved pieces are really good to use immediately after
a magnetic cannon. If you need to put a curve after a magnetic cannon, sometimes the marble
can shoot off the track. But these will keep it on the track, so these are really useful.
nd next we have two of the tunnel switches. Ao there's a little switch piece that goes inside
of it. You can't set the initial position of that switch, but it will toggle, so that each time a
marble goes through, it will alternate on the exits. Left, right, left, right. Or right, left,
right, left, depending on the initial position of that switch. So you get two tunnel switches.
Next we have two of the vertical u-turns. What these do is they drop a marble from a platform,
from the edge of a platform or maybe a balcony, down to a platform or balcony or tile below it.
And they just hook onto the edge of those tiles, and the marble will drop down,
pick up some momentum as it goes. So these are really helpful and useful pieces.
Pretty neat.
Additionally we have some unique track pieces which were first introduced in this Tunnels Set.
You have two of the long Bernoulli tracks. These are really great for
accelerating a marble into the looping expansion.
And in addition you have one each of the convex and concave drop track. The marble can
actually drop through that hole in the middle if it's going slow enough,
or if it's going fast enough it'll pass right over.
Additionally we have two track ball catchers, which go on any of these silver gray tracks,
and what they do is they catch a ball falling from above,
kind of capture it onto the track, and allow it to
go out the side and on its way down the track. So you can do a lot of tricks with those.
And lastly you get two base plates in the this Tunnels Expansion Set, so that's really cool.
So there's a lot of very useful pieces in this Tunnels Expansion. I highly recommend it.
Just so you know, there are some starter sets that now contain some of these pieces,
which are the Speed Starter Set and the Giant Starter Set.
