The Lifter expansion, as might be obvious from the name, lifts marbles vertically to three different levels depending on how many pieces you use to build it. It needs to be manually operated each time by a button and can send marbles in different directions at the top. What’s in the Box? We also talked about the Gravitrax Expansion Catapult in terms of density – thinking about what would happen if the balls had been designed lighter. We came to the conclusion that they would not have travelled as fast or as far. This resulted us in thinking about weight restrictions on rollercoasters. The Gravitrax Add-Ons: Action Loop Add-on

I was surprised with the consistency here, simply because of how energetic this expansion is. I expected the marbles to go flying off all over the place, but they went where they were supposed to the vast majority of the time. GraviTrax is a toy I love and will recommend again and again, and these expansions will serve to make it even better. GraviTrax CORE, PRO or POWER? Preferably all three, of course. But one thing at a time. First of all, we would like to introduce the three different GraviTrax lines here and answer the most frequently asked questions: Which GraviTrax products are suitable for beginners? What is the difference between GraviTrax PRO and POWER? From what age can you start having fun with GraviTrax? We then put into practice what we had learned about rollercoasters using the Gravitrax add-ons by making our own out of junk materials.As it simply carries a marble along in the same direction it came from with no level shifts, this is one of the easiest GraviTrax expansions to incorporate. The Gravitrax Expansion Catapult allows further development of STEM through trial and error, plus some discussion. We experimented with varying the height of the catapult: We wanted to determine whether the higher the balls are flung from has any effect on how high has and/or far they will travel to get over an obstacle. To see how far the ball went we measured it in terms of tiles it passed; and for height we built a tower that is crashed into, lower it a tile at a time to determine when it could pass. Of course the answer is yes – the higher you place your catapult the higher and further the ball will travel. The set comes with a large book of construction plans, graded by difficulty level. When you are familiar with the different pieces and how they fit together you can move onto the tasks. These ask you to complete layouts by solving a variety of challenges which are graded by difficulty, for example working out how many height tiles you need to add or which elements are missing. The Flip is a lot of fun to watch. I think it was probably my favorite of all the GraviTrax expansions so far.
