Magnetic Sky

Mark Schneider — Wed, 22 Mar 2023 17:18:17 +0000

Magnetic Skies by Ioannis Michalou(di)s are unique and beautiful visual creations born from the unusual properties of silica aerogel. Each Magnetic Sky consists of pure silica aerogel embedded with metal filings, frozen forever along the magnetic field lines present during the artwork’s creation, in a unique form which can never be repeated. The aerogel is contained within a slumped champagne flute, and provided with a wooden display frame that can be mounted on the wall or placed on a desk. The technical craftsmanship that goes into creating each artwork is truly unparalleled. Magnetic Skies are blue in front of a black background, virtually invisible in front of a white background, and cast a shadow with a golden hue reminiscent of the sun’s rays. A special gift for that special geek in your life.

Two of Michalou(di)s silica aerogel artworks are on MoonArk’s “Moon Museum” rocketed to the moon on May the 4th, 2023!

Bottled Sky

Bottled Skies by Ioannis Michalou(di)s are a unique and beautiful visual creation born from the unusual properties of silica aerogel. Bottled Skies are blue in front of a black background, virtually invisible in front of a white background, and cast a shadow with a golden hue reminiscent of the sun’s rays. Medium Bottled Sky consists of pure silica aerogel cast into a signed, individually numbered bottle accompanied by a combination red laser/white LED keychain to experience the striking optical properties of aerogel firsthand. Large Bottled Sky consists of pure silica aerogel embedded with a “cloud”, unique in form and which can never be repeated. A special gift for that special geek in your life!

Medium Bottled Sky – 2.0 cm x 8.5 cm, with LED/laser keychain
Large Bottled Sky – 2.5 cm x 10 cm, with embedded cloud

If you think the ethereal blue of Classic Silica™ aerogels is mesmerizing, Colored Aerogel Discs from Aerogel Technologies will amaze you even more. Spun-off from a top-secret Aerogel Tech project, these exotic aerogels are infused with optically-active materials that impart fascinating visual properties such as casting a colored shadow and color shifting under different light sources. Like their classic blue cousins, these aerogels exhibit the “frozen smoke” effect of revealing the path of light rays passing through the material making them ideal for visual art and sensor applications. Makes a fascinating display piece or gift for the scientifically-inclined. Density is ~100 mg/cc making these aerogels ~96% air by volume. Dimensions are ~2.3 cm x 1.0 cm.

Aeroeggs

Aeroeggs from Aerogelex are unique aerogels made from hard-boiled eggs. While many people think of space-age blue holographic solids made of silica when they hear the word aerogel, aerogels can actually be made from a wide variety of substances including biopolymers such as those found in eggs. Aeroeggs are made through supercritical drying, the same process used to make other aerogels, just using boiled eggs instead of silica or polymer gel precursors. Boiling an egg causes the proteins in the egg to denature and link together to form a gel matrix that contains water in its pores. Once the inside of the egg has congealed, the shell is removed and the boiled egg inside is soaked in ethanol to replace the water in its pores with a non-polar solvent that is compatible with supercritical drying. After soaking the egg is put in a high-pressure vessel and the ethanol in its pores is extracted with supercritical carbon dioxide to make an egg aerogel. Aeroeggs are made from ordinary chicken eggs but are about half the size of a typical hard boiled egg due to contraction of the egg protein network when the water in the egg is replaced with ethanol and carbon dioxide. Density is approximately 0.6 g/cc making Aeroeggs approximately 50% air by volume. Aeroeggs absorb 3x their weight in water to irreversibly rehydrate back into regular hard boiled eggs. Aeroeggs are not only fascinating materials but are also useful for scientific research, medicine, and personal products. Biocompatible aerogels such as egg aerogels serve as valuable porous scaffolds for drug delivery, time-release fragrances, and tissue replacements. Aeroeggs come as monolithic egg halves packaged in a transparent decorative openable hanging ornament. Like Humpty Dumpty, Aeroeggs are fragile and cannot be put back together again once broken, so we suggest you buy a discounted two pack so you can have one to keep and one to experiment with. Aeroeggs make great gifts for food nerds and science geeks and are great for science project explorations. Aeroeggs are not edible. Do not eat. Although Aeroeggs are made from real eggs and in principle egg aerogels could be eaten if prepared properly, these aerogels are supercritically dried in industrial equipment that processes chemicals and that is not food grade making them not edible. Seriously don’t eat them, not even rehydrated. Food grade Aeroeggs available soon. Made in Germany. Packaged in USA.
