MolCraft | Molecules in Minecraft
Minecraft is a fabulous tool for exploring structures of buildings, landscapes and even anatomy. So why not molecules?
So as part of an undergraduate project, students in the Department of Chemistry at the University of Hull (and supported by the Royal Society of Chemistry) have populated a Minecraft world with structures of proteins, chemicals and even some chemical history.
You can download the MolCraft and run it locally on your own machine, explore the world via our server, or use the schematics of the molecules to populate your own worlds with molecules.
Whatever you do with it, please share your results with the Minecraft community and let us know what you are getting up to via email or twitter using the hashtag #MolCraft.

How we built MolCraft
Protein structures are stored in the protein database. We figured out how to port these into Minecraft. It is a process that involves a number of pieces of software, all of which are free. The workflow is detailed here. If you can figure out a quicker way please let us know! The protein data bank also exists in Europe and has its own website.
Other molecules were built with the free software Avogadro and then ported into Minecraft using a similar system.
What am I looking at?
Chemists often build ball and stick models of molecules to help visualise them. The balls represent atoms and the sticks are bonds between them. By convention different atoms are represented by certain colours. We’ve stuck to this colour scheme by using dyed wool blocks.
|White wool||Hydrogen||Yellow wool||Sulfur|
|Black or dark grey wool||Carbon||Green wool||Halogens|
|Red wool||Oxygen||Purple wool||Phosphorus|
Proteins are long thin molecular chains with many branches coming off them. If we showed you all the atoms in the chain and the branches then it would just look like a right mess. So instead we’ve used another convention, where a ribbon represents the chain and all the individual atoms are not show (unless they are particularly important).
What can I do in the MolCraft?
You can just explore and read the info about the molecules. But there are also a whole load of treasure chests dotted around filled with goodies, puzzles and quiz books. Some are easy to find, others are fiendishly difficult. If you locate them all then you’ll probably have learnt a fair bit of chemistry along the way!
MolCraft is available in the EDU world library for use in schools. If you are a teacher and want to use it then get in touch and we can provide you with more supporting information.
