Great chemistry gift Amazing science gift Sweet Stocking stuffer, Christmas gift Aerogel goes by many names blue smoke , solid air but it's comely called the world’s lightest known solid. Some facts about aerogel Aerogel is also the word's most effective thermal insulator, 39 times better than the best fiberglass insulation. aerogel has a slightly blue hue, the best (in the of the creator) back drop for the necklace is on a black shirt for the best contrast. NASA uses aerogel to trap space dust from comets aboard the Stardust spacecraft. Beforehand the dust would vaporize on impact with solids and pass through gases, but they can now be trapped in aerogel's tightly woven Nanostructure. NASA also has used aerogel for thermal insulation in the Mars Rover and space suits. Aerogel is brittle but very strong under presser Aerogel is also extremely hydrophobic. This sample is great for fun science experiments and Collections FYI: If the vial is broken know that Silica based aerogels are not known to be toxic. Although, they are an irritant to the eyes, skin, respiratory tract. Please do not attempt to break open vial. Review: Great necklace - First of all, the necklace is great. Perhaps the tube with the gold is smaller than it looks, but it is cool anyway. There is a stainless steel clasp and I am not sure what the tube is made of. It is not steel as it is not magnetic. The tube’s clear part is glass. I had to dock a star as the glass part had residue on it, but goo gone is fine. The bottom is a bit scratched up, too, but no one sees that I assume. ## Features - Worlds Lightest Solid - One of a kind necklace - First ever aerogel & pure gold necklace ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01BFYCMRS | | ASIN | B01BFYCMRS | | Age Range Description | Adult | | Brand Name | silica | | Chain Length | 22 Inches | | Chain Type | Cable | | Clasp Type | Spring Ring | | Color | blue, clear, gold | | Customer Reviews | 4.3 4.3 out of 5 stars (4) | | Date First Available | September 3, 2015 | | Is Discontinued By Manufacturer | No | | Item Dimensions | 1 x 0.5 x 0.5 inches | | Item Weight | 5 Grams | | Manufacturer | Chemistry Cabinet | | Manufacturer | Chemistry Cabinet | | Material | Silk | | Primary Stone Gem Type | No Gemstone | | Product Dimensions | 1 x 0.5 x 0.5 inches; 0.18 ounces | ## Images ![Silica Aerogel & Pure Gold Necklace - Worlds Lightest Solid - Image 1](https://m.media-amazon.com/images/I/81-ahNRbYHL.jpg) ![Silica Aerogel & Pure Gold Necklace - Worlds Lightest Solid - Image 2](https://m.media-amazon.com/images/I/41drgPkgBWL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐ Great necklace *by F***E on January 9, 2019* First of all, the necklace is great.
