Super Cereal.

Looking at the ingredients labels on food can be both an insightful and frightening affair. I’ve long been in a habit of doing it and I always find it fun to research some of the more esoteric ingredients, well that is right up until I find out where some of them come from. It’s the old adage of not finding out how the sausage is made, although in reality you should probably consider that with all things that you put in your body. Still when I watched the following video I was honestly surprised to see the outcome, as I didn’t think the effect of extracting iron from cereal would be so dramatic:

The first half of the video explores the idea that there’s elemental iron within cereal which can then be attracted by a magnet. Whilst this is true to some degree, the iron within the cereal will feel an attraction to a magnet, you can actually perform the exact same experiment with cereal that is bereft of any elemental iron content. This is because water is a diamagnetic material which is a fancy way of saying that in response to a magnetic field it will create its own inverse field in response. For the cereal and magnet experiment this means the water actually divots around the magnetic field which the piece of cereal then falls into. The iron in the cereal helps this process along of course, but it’s not the only force at play here.

However the extraction of the iron from the cereal was pretty astonishing, especially considering just how simple it was to do. Trying to extract other elements from the cereal would prove a much harder endeavour which is why I think an experiment like this is such a powerful visual aid. You’re literally seeing the iron being pulled from the food you eat which, in turn, makes you think about all the other things that are listed on the ingredients label. It might not be a particularly pretty picture that you end up with, but at least you’ll be far more aware.

I wish I knew about these kinds of science experiments when I was a kid!

Minecraft: Addictive Simplicity.

Sandbox games and I have a sordid history. Whilst I often enjoy them it’s not usually because of the engrossing story or intriguing game mechanics; more it’s after I’ve finished the mission at hand, saved my game and then promptly engage Jerk Mode and go on whatever kind of rampage the game allows me. Long time readers will remember this being the case in my Just Cause 2 review where I grew tried of having to do everything within the rules of the game and modded my way to Jerk nirvana. Still there have been some notable exceptions, like Red Dead Redemption, where the combination of certain elements came together in just the right way to get me completely draw in an engrossed in the story.

Minecraft, whilst sharing the sandbox title, has almost no elements of a traditional game in this genre. Having more in common with game mods like Gary’s Mod Minecraft throws you into a world where the possibilities really are only limited by your imagination. Over the past few months I have watched the news around it go from a single story to a media storm and I was always fascinated by the way it managed to draw people into it. Up until a couple weeks ago however I hadn’t bothered to try it for myself, not even the free version. However after watching a few videos of some of the more rudimentary aspects of the game I decided to give it a go, and shelled out the requisite $20 for the full (beta) version.

That’s a deep mine…

The premise of the game is extremely simple. You’re thrust into a world where everything is made of blocks and at night time hordes of zombies and other nefarious creatures will emerge from the wilderness, baying for your blood. The tools you have at your disposal are only your blocky hands but the world of blocks around you can be used to your advantage. By cutting down trees you can make wood which can then be converted into a whole range of tools. The race is then on to create some kind of shelter before nightfall comes, so that you might have a place to hide when the horde arrives. As you progress deeper however you’ll begin to discover other rare and wonderful materials that can make even better tools and weapons, leading you to delve even deeper underground in order to find those precious resources.

However whilst the basic idea extends to only surviving through the night there’s the entire meta game of creating almost anything you can think of within the Minecraft world. The world’s resources are pretty much at your disposal and their block like nature means you can build almost anything out of them. This has lead to many people building extremely ornate structures within Minecraft, ranging from simple things like houses right up to the Starship Enterprise. As with any sandbox game I took the opportunity for absurdity as far as I could imagine it at the time building a 1 block wide tall spire high up into the clouds where I mounted my fortress of evil.

All that’s missing is an Eye of Sauron.

The basic game mechanic of Minecraft has a dinstinctly MMORPG feel to it. You start out by cutting down trees for wood so you can make a pick axe to mine cobblestone. You then use the cobblestone to make better tools in order to mine iron. You then use the iron to mine other resources like gold, diamond and redstone. Much like the gear grind that all MMORPGs take you through before you’re able to do the end content Minecraft gets you hooked in quickly with the first few resource levels passing quickly. Afterwards it’s a much longer slog to get the minerals you require to advance, usually requiring you to dig extremely deep to find them. Like any MMORPG though this mechanic is highly addictive, leading me to lose many hours searching for the next mineral vein so that I can craft that next item.

After the first week however I started to grow tired of the endless mining that didn’t seem to be going anywhere. I had dug all the way down to bedrock and had found numerous rare resources but seemed to be lacking the one mineral I needed to harvest them: iron. Googling around for a while lead me to figure out that I was digging far too deep to find much iron and that the best place to find resources was in randomly generated dungeons or caves, basically pre-hollowed out sections of the map that were always teaming with resources (and zombies). After randomly digging for a while I started hearing the distinctive zombie groan and I followed it to the ultimate prize.

Oh yeah, that’s the good stuff!

Exploring this find lead me onto a string of caves all containing the resources I needed to progress further and I was hooked again. Whilst the last few hours I’ve spent with Minecraft have focused more on extending my fortress of evil and the surrounding area I still find myself often taking a trip down into the mines in the hope of coming across another cave or mineral vein as the excitement of finding one is on par with getting some epic loots in a MMORPG. I also set about setting up a Minecraft server so that I could play along with some of my more dedicated Minecraft friends although with a server fan dying I’ve had to put that on hold until I can ensure that it won’t overheat with more than one person playing on it.

Would I recommend this game? Most definitely, especially if you’re the type that enjoys sandbox style games that allow almost unlimited creativity. I was the kind of person who lost hours in Gary’s Mod, making whacky contraptions and using them to unleash untold torment onto hordes of Half Life’s NPCs. The tables are very much turned in Minecraft’s world but it’s just as enjoyable and I have no doubt that anyone can lose a few good hours in it just exploring the retro world that Minecraft generates for you. The game is still technically in beta but for the price they’re asking it’s well worth the price of admission.

Minecraft is available for PC and web browser right now for a free trial or AU$20. Game was played on a local single player instance for the majority of game time with an hour or so spent on a multiplayer server. No rating is being assigned to this game as it’s still in beta.
