Our glow in the dark graphene sheet model uses special phosphorescent bonds to represent electrical conductance that makes it interesting for use in high efficiency capacitors; only $33.95.
Or have fun with it on Hallowe'en & go out as the "Graphene Ghost". Put on black top and wear one front and back.
This kit can also be converted in to a graphite crystal structure model with some extra parts. You will need to add several trigonal bipyramidal atoms and some of our 70mm Indigo "Wobbly™" bonds for connecting the layers.
