Magischer Magnetismus

Man kann es Murmelbahn nennen oder auch Rube-Goldberg-Maschine – ganz egal: Was der YouTuber namens Kaplamino gebaut hat, ist schön anzuschauen und nutzt einige physikalische Effekte souverän aus.

Was der YouTube-Nutzer mit dem Pseudonym Kaplamino auf einer offenbar schräggestellten Holzplatte mit Kirschbaumfurnier angeordnet hat, fängt erst einmal an wie eine simple Murmelbahn, die vielleicht noch Dreijährigen die Kinnlade herunterfallen lässt: Eine Glasmurmel folgt der Bahn, die ihr von ein paar Holzleisten-Stückchen vorgegeben wird. Aber was sich dann im Lauf von rund vier Minuten auf insgesamt 16 Bildausschnitten abspielt, fasziniert auch Erwachsene: Wechselweise Murmeln und Stahlkugeln absolvieren einen vertrackten Parcours und lösen ausgeklügelte Mechanismen aus, bei dem Schaschlikspieße Impulse übertragen und pendelnde Papierstückchen einzelne Kugeln auf die richtige Bahn bringen. Auch Münzen, Dominosteine und eine Schere sind mit von der Partie.

Magnets and Marbles ! [4:04]

Hey ! After 3 domino videos, Marbomino is back ;)
In this project, I use those little magnets that can be used to make cubes and others geometric figures, I think the name is "Neocube".

It's really impressive how many tricks you can do with that, at the beginning I didn't think that I could make a whole project based on those magnets, but finally, it was pretty easy and I think there is still lots of cool tricks to discover !

I like this kind of video when I can't do what I want, I'm forced to think of tricks with magnets in that case. It's the opposite of my video "Random screen link" when I just build all the thing that come to my mind, constraints are good for the creativity it allows to find original tricks that no one has thought (I think, because I've never seen something like this on youtube). It reminds me my project "The New Trick" after rubber bands, let's use magnets ;)

I think this project is the best one of the three I did with marbles, but there are still a little problem : the lighting.

Because now that I'm in a small appartement for studies, there is only one window on my room, it's not a big one and I don't have powerfull lights. That's why some of the ideas in this screen link seems to be darker than others, you can litteraly see the difference when a cloud passes over the sun (and it's happend 2-3 times).

It's also the reasons why I made a project with marbles, in a small room it's easier than dominoes, even when you have a long table !

- Why the video has taken so long to come out ?

Yeah, I know ... but let me explain, because there's many reasons :

First, I had to buy marbles and magnets on ebay, I waited 2 weeks for the delivery. Then I made a first screen link but it was bad because of a format problem on my camera. The movie was jerky and the lighting was terrible because I tried to use artificial lights (very bad idea ).

Also, this screen link was supposed, at the beginning, to be a big machine in one take on my table, but I give up after 50 fails, maybe RGM is not my thing. Maybe I just need to try with more reliable tricks ^^

And the last reason : I'm lazy and perfectionnist, with those two things it's hard to finish a project, because I have this idea in my mind since 3 months maybe, and I work really hard for only 4 minutes at the end (domino builder is a hard job) .But trust me there is more work in this project than you can see in this video, because of how many times I start from scratch.

You can see that this description is bigger than in my other videos, because this time I had lots of things to say, and I realize that it's better for you to know the background of a project.

If you read all this description, thank you and sorry for my bad english, I'm not used to write long texts like this, but I hope it was interesting and I hope you like my video ;)
