Review - Geomag Mechanics - Gravity Shoot & Catch


Geomag magnetic construction sets are fun and educational STEM (Science, Technology, Engineering and Mathematics) toys for all ages and in many price ranges. Hours of magnetic fun without the need for screens!

What we thought…

*for less drivel about us and more about the product, scroll to the end.

The Gravity Shoot and Catch set helps you build a track which is like a magnetic marble run. Using a combo of gravity and magnets, you can send a steel ball from one end of the track to the other via some some cool obstacles you’ve made yourself using magnetic forces and all sorts of science. (for a more in depth look into this science, look below).

We have science brain’s in our house (not mine obviously, I’m more Corrie than QI etc let’s face it) but Rocky and his Dad have those kinds of brains where, metaphorically speaking, they will pull things apart and try and work out how they work before they use them, even if it is just a doorbell. Therefore anything science based is now a big bonus in our house, especially if it is something they can do together. So when Geomag sent us this little beauty in the post…. I panicked and passed the buck to the bald one and made him indoors do it. My brain hurt just reading the box. (see what I mean below!)

The movement of the Mechanics models wins over gravity with the Gravity Shoot & Catch set. Thanks to the magnetic motor, the Geomag spheres move up along a never-ending spiral and reach a circuit of amazing magnetic tricks. Here is the “Stop&Go” trick in action: two magnetic rods, positioned with opposite polarities, can keep one or two spheres perfectly still inside a chute. When a third sphere joins the other two from above, it is itself trapped by the magnet and the lowest positioned sphere is released to continue its journey along the circuit. This Gravity set contains 11 magnetic rods, 36 steel spheres and 196 plastic mechanical elements. These gears are essential to harness the forces of gravity and magnetism. Gravity is the innovative evolution of the Geomag Mechanics line. Developed with expert players in mind, the new construction system is based on an innovative “gravity motor”: this uses the weight of the Geomag spheres to kickstart the mechanisms and movements of the Geomag Mechanics structures. The motion is provided by the invisible forces of Gravity and Magnetism, without using electricity or batteries. The play experience is based on these fundamental principles of physics. Mechanics Gravity is a STEM product that can truly stimulate curiosity and inspire to learn more about science.

Right the nitty gritty, think Meccano but on steroids…. this is bloody tricky, even for an adult, or maybe it was just Hoff. It was hard to watch him try to set it up and bite his tongue instead of Rocky’s head off when he tried to ‘help’ him. '“Fiddly and wobbly” were Rocky’s description words of the set up but when asked if he had learnt anything he did respond with some cracking STEM (science, tech, engineering, maths) analogies which was a bit of a shock to my ears. So obviously it does do the learning aspect trick.

It has 2 instruction manuals, the first explains how to make the various mechanisms; the magnetic transmission, magnetic cannon, gravity motor, stop and go and magnetic catcher. The other has step-by-step instructions on how to put together the tracks… easier said than done. Don’t try with false nails.

I think this might be a group activity for maybe a class of 9-11 year olds (year 5 or 6’s) and their teacher or an older child who really like’s to build. I would say age 7 alone might be pushing it a bit. It is clever though, I might lend it to Rocky's friend’s in Year 5 or 6 at his school to see what they think and then update you below. I like to get a different perspective sometimes, makes for more interesting reading.
