3D-printed titanium chainmail fabric
It was created using Direct Metal Laser Sintering (DMLS), a technique that fuses titanium powder with a laser to form strong, corrosion-resistant structures, often used in biomedical and aerospace applications.

Disappearing Spoon
The metal gallium has a melting point of 30°C (86°F) and will melt quickly when exposed to tea-temperature hot water - or melt in one’s hand if handled too long.
This spoon was made with a silicone mould and feels and sounds just like a regular spoon, except solid gallium is brittle and the spoon can shatter like glass if dropped. An amazing parlour trick as well as a classic and historical class demonstration.

Landowner David Hampton planted larch pines in a Douglas fir forest in Oregon in the shape of a giant, 300 feet smiley face 🙂
Every autumn, the larch pines turn orange, and the smiley face stands out.

The thinner tree was cut years ago and the big one has been holding and feeding it since then. They "wake up" together in the spring and "go to sleep" together in the autumn.
Inosculation is a natural phenomenon in which parts of two different trees, commonly but not exclusively the same species, grow together, self grafting and sharing nutrients.
The term emanates from Latin osculari, to kiss.
