Disappearing Spoon

Gallimum metal and a silicone mold to produce the spoon- available here:

From Amazon: BUY NOW: Gallium Mold Spoon Kit 

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 mold (swipe to see process), 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 parlor trick as well as a classic and historical class demonstration.

Tessellation Origami

Contact her to buy her artwork, or you can buy her books and learn how to fold amazing geometries!

From Amazon: BUY NOW: Ekaterina Lukasheva: Papercraft and Origami

Tessellation Origami: nested spirals and triangles created from one flat sheet of paper! This beautiful work by Ekaterina Lukasheva also demonstrates how folded paper can obtain very different physical properties than that of the original flat paper. When stretched out this paper sculpture prefers to snap back into spirals and triangles, and although most materials bulge out when compressed along one direction, here the design compresses evenly along all three axis of the hexagonal symmetry.

Bobile: Balance + Mobile

This vintage item often available here:

From eBay: BUY NOW: Bobile Balance Art Toy

Bobile: balance + mobile— all components have a skid resistant rubbery coating which provides for static friction to allow for many interesting configurations. I obtained this fun toy from the SF MoMA gift shop a few years back- made by Hog Wild Toys LLC where a blurb on the side of the packaging claims “Where the science of physics is applied to the creation of art”.


Vintage Bulb Spectra

Get this diffraction grating here: explore light source spectra! 

From Amazon: BUY NOW: 500 line/mm diffraction grating

Vintage Bulb Spectra: emission line spectra identify the gas within these two vintage discharge glow bulbs- revealed here by a 500 line/mm diffraction grating. The color of each gas is due to a mix of the colors emitted from electron energy transitions specific to each element, the basis of spectroscopy.
