Make a Coil Train

No doubt about it, electric trains are cool.  They are expensive though.  And you could get called “a nerd.”  But really, those people are just not cool, so there.

Follow the simple 4 step instructable to make “The Simpliest Electric Train“.  Now, watch the video of it in action.  It’s quite cool.  Except the jumps, that part sucks, don’t build this expecting to get some sick jumps.  You’ll be dissapointed.

If your kid, or brother, or friend wants a Train for Christmas.  A. Get them one, (if they’ve been a good child that is). B) If they like trains, then they’re probably interested in science.  Why not spend $20 and make this with them.  It will be cool and get them interested in science.

Magnet Fishing

magnet finds

Did you know of this “sport”  I never heard of it until I stumbled upon this imgur album.  Basically, people attach a strong magnet to a rope and throw it into rivers and bodies of water hoping to find sunken treasure, or murder weapons, or un-exploded ordinance.  In reality, all they seem to find is rusted crap, but hey, they’re cleaning up the environment, so good on them.

The sport is pretty dull, the commentary on the photos is what makes it fun.  I can’t say the same for the rest of the subreddit dedicated to this sport, but there are some interesting finds in there.

Magnetic Clock

Ferrofluid is a pretty neat substance.  Tiny, often magnetic microscopic particles are suspended in a liquid.  Then, using regular magnets, or electromagnets, you can control what they do.  It has many practical uses, but also the below artistic one (which also has a practical use as a clock).

You can buy the said clock, but it’s an “art piece” and comes with an “art piece” price of 7,500 euros, which at current exchange rates, is over $8,400.  That’s alittle too much for me.  Plus, the magnetic material only has a 1 month lifespan.  I’m not sure why, but that means you would have to by replacements of that stuff for probably an equally high price.
