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.

Trick Cutlery

This Instructable will show you how to make your own Gallium Spoon.  Unlike the trick spoons from the movies, this won’t form back into a spoon when you take it out of the water, or soup.  Also, I’d make sure you have lots of extra soup, because while gallium might be non-toxic, I don’t think most people would be ok ingesting it.

Simple Salt Water Purifier

Don’t worry, you’ll probably want something like this after yesterday’s post.

Salt Water Still

Or in other words, a still.  That’s basically what Eddie the Invemtor has made.  It won’t make you and decent booze, but it will purify water for you enough to drink while you’re in the woods.  I’m not sure if I’d carry these things around with me all the time, especially with the rest of the stuff I currently have in Alaska.  I’m also not sure where I’d get salt-water in the woods, but dirty stream and puddle water, that’s easy enough to find in the woods.

Coke Shotglass

If you ever wanted an edible shotglass made of coke, this video is for you:

Honestly, the rubberness of it looks weird to me.  I would prefer if it were frozen.  It would probably feel better while you drink from it.  The glass wouldn’t last long, but that’s the idea I bet.  How would warm gelatiny coke taste?  Probably strange.

Survival Fire Piston

lathed

Instructables user wartellc made his own Fire piston in about 4 hours.  I had never heard of one of these before, but the concept is pretty basic, I like it.  I don’t have any of the tools necessary to make my own, so I’ll probably just buy one, it’s only $25 on Amazon.  However, the char cloth that is necessary to really use it, that I can make according to this instructable.

Char Cloth is dead simple to make, take an old, 100% cotton t-shirt, cut it up into small pieces and put it in a sealble tin container.  Punch a small hole in the tin, and place it on a fire/ember.  When no more smoke comes out of the tin, you’re finished.

Now you’re ready to use your fire piston to make some fire!

Pipe Lamp

finished lamp

Instructables user Matt2 Silver has a really awesome DIY aged bubbling pipe lamp.  He did a fantastic job on the whole thing, I thought it was a real copper pipe from the initial photo and video, but it’s really PVC.  The small touches of mixed white and green paint for oxidation are really nice.  The hammered paint applied to the PVC looks really realistic.  I approve of this project.

In case you can’t figure out how it works, here’s a schematic of it:

I really like it, it’s pretty simple and unique.  A kid would love it probably.  I think it would be a great project to do with a child so they have a unique conversation piece for their friends.

Here you can see him measuring the threaded rods that connect the top.  I know why he choose a clear bottle, this way he could change the water color at a later date.  Personally, I think green looks best, so why not skip a step and use a green wine bottle.

DIY “Lava” Lamp

It’s more of a controlled reaction of acids and bases then the soothing blobs from a true lava lamp, but this instructable is dead simple to follow and can be quite fun.  I bet if you got something a little thicker then vegetable oil it might be a slower process that’s more true to the lava lamp.

In other news, did you know the Lava Lamp was recently updated to use ferrofluid?

It went through the Kickstarter campaign and was successful and now you can buy it!  It’s quite expensive for a lava lamp at $150, but hey, technology.

Fun with Magnets!

Powerful permanent magnets are fun to play around with and experiment and learn from.  Aptly named Instructables user Magnetic Games has a short 2 step instructable that  shows how to make a few neat things.

Actually, his YouTube channel is full of interesting experiments and toys you could make with ease with magnets.  I think the gears are pretty cool, and of course the accelerators are awesome, very MAC cannon like, which is a type of rail gun.

Unfortunately, none of these things are perpetual, so they won’t solve all the world’s problems at once.  But they will get kids thinking of new ways to try things, and with better electricity, and better components, we might be able to come up with innovative ways to do things using magnets.  Because Magnets Bitch!

5th Element Candle Holders

Candles

At first, I thought the whole sculptures were candles, but it’s just holding tea-lights.  That’s kinda lame, but it still represents the final scene part of the excellent movie The 5th Element.  I did learn something though, there was a rhyme and reason to the wavy lines on each stone, I thought they went around the whole stone, but they are different on each side.

LEGO Mini-figure candles

Candles on Cake

Instructable User Hey Jude has put together a quick instructable on how to make your own LEGO Min-figure molded candles.

Using a product called Sugru to make a mold of the min-figure, then pouring in a tablespoon worth of melted wax into the mold.  Allowing it to dry for 30 minutes gives you finished product, which you can then melt to your heart’s desire.
