I’m not usually one for seasonal decorations, but my sister had a thing about setting up a killer Christmas tree in Misfitville. It was impossible to close the curtains in the evening without being jabbed by a deadly mass of pine needles.

However, there is a host of science themed decorations on Etsy to defrost even the most hardened humbuggy of hearts. Just don’t expect it to actually be made out of rare earth material Holmium.

Many of them make use of the periodic table, though I don’t know if they have been suitably updated. You can also mix it up with DNA, physics, psychology, dinosaurs and Firefly.
