Gravitrax Expansion Trax and Add Ons

Summer holidays boredom? No such thing, if you have a GraviTrax play set in your house. Young engineers will have a blast, testing the power of gravity and using their imagination, while building dazzling engineering constructions, from easy-peasy to super-complicated.

We have already reviewed a GraviTrax starter set earlier this summer, and today we'll show you how you can expand the set.

I can promise you, you will get hooked.

The STEM system - Science, Technology Engineering and Maths - is a super tool to teach children about gravity, magnetism, kinetic energy and fun.

For all add-ons which we show today, you will need a GraviTrax Starter Set.
It is suitable for ages 8+, but a younger child will enjoy it as well, with an adult supervision (but not the preschoolers due to small parts).

GraviTrax Expansion trax (£19.99) is only playable with a starter set. It promises to take your run to a whole new level.
The set contains 16 large height tiles, 8 small height tiles, 7 curves, 1 junction, 1 long track, 2 medium tracks, 3 short tracks and 6 balls.
It is an excellent add-on set, which allows you to expand your engineering construction even further.
We'd love to have a booklet with instructions and blueprints, and new models and tracks to build, with step by step, but it doesn't seem to appear with this set.

The Gravitrax Loop adds another cool element to the layout. You need to employ your engineering grey cells to figure out how to make the sphere shoot through the loop and keep on going rather than falling flat inside the loop.

We shot a series of very short, a few seconds-long videos to show just how the loop works.
We recreated the tracks A and B from a tiny leaflet with blueprints, which was very helpful.

Track A from the instructions leaflet.




And in case you missed the looping action, here it is in slow motion, close-up;




Moving onto the second track from the instructions:




And again, the looping bit in close up and slow motion to see how the ball makes the loop:




Very impressive add-on.

We were less successful with the Gravitrax Add On Catapult. It looks pretty cool, and is not that difficult to assemble, but the arm with the bucket does not stay lowered down. It's possible the rubber band is too tight, as it's brand new.

In theory, you should be able to throw mini-spheres in the air and make sure they land and finish the track.
I will wait to see how the other bloggers make it work, and hopefully figure it out.
