20 balls, 30 balls, 40 balls and still it was possible to grab last rod on top of the basket and lift everything above the ground. Finally, we were able to put 51 balls into the basket and with just one rod was still possible to lift it up. With 52 balls inside, basket was too heavy.
Total maximum weight of basket and balls was 740g on our kitchen scale.]]>
228 rods, 85 balls.]]>
It seems that Geomag is not very good for construction of Gauss rifle, one problem can be with different size of balls and rods . If the size would be the same it would probably work better.
I have used just two rods, 7 balls, wooden track, piece of paper between rod and wooden track (to put middle of the rod into the same height as middle of the ball in the track) and sticky tape to attach paper and rods to the wooden track.
Prepare piece of wire about 10 cm long with both ends skinned off.
From Geomag pieces (8 rods and 5 balls), build a small pyramid with all rods on the bottom in the same color. One different rod will help you to see movement. You also want to maximaze magnetic power, so all rods connected to the top of the pyramid should be with the same polarity (if you remove ball, each rod should repel all others).
Than, add sixth ball to the top of the pyramid and connect that pyramid to the bottom of battery. Hold a battery in your hand, connect one end of the wire to the top of the battery and second end to the ball which is on the top of the pyramid.
You should have something like that at the end.
Be carefull, wire can become quite hot after a while, you may want to wear gloves or otherwise protect your skin…
Original idea comes from http://www.supermagnete.de/, I have replaced their super-magnet with Geomag pyramid…]]>
If completed, this snowman will have 507 rods without any reinforcement.
But anyway, I don’t plan to repeat this construction soon, I will start with something else.]]>
It should be enough even for bigger projects
(some pentagons don’t have the right color, I will change it soon).]]>
I have added almost twice our previous collection - 360 rods, 240 balls (10xGeomag Color 60) and 3 packages of pentagons.
Unfortunately, it seems that I still don’t have enough pieces. Currently missing some plastic - mainly squares.
I have started with “big” ball. Such a big ball was not possible to make with only 180 rods from previous collection.
From this point I had to worry about stability of the ball - I had used all squares available, so all squares on the top of the ball remained without any support.
But finally, I have managed to complete first ball. For the second ball, I had to use smaller size than planned - again, no squares.
You can see also yellow rods inside first ball - as a reinforcement, to be able to carry other two balls.
All balls completed, just to add some final touch and snowman is complete.
|Blue: 174 pcs, Green: 132 pcs, Red: 57 pcs and Yellow: 54 pcs|
And after that, you can create a picture, displaying what you have bought. Like me.
And you can try to build something. Like a pyramid or Eiffel tower or electromotor…]]>
