THE ELEMENTS

In the past, glass manufacturers added uranium to glass for color. Uranium has since become more strictly regulated, but the old uranium glass objects are still floating around. Because of the uranium content, these marbles glow bright green under ultraviolet light. ...

Musket Ball:  Muskets were smoothbore muzzle-loading weapons, firing round lead balls or buck and ball ammunition, that were also designed to accept a bayonet. This style of musket was retired in the 19th century when rifled muskets (simply called rifles in modern terminology) became common...

WE LAUNCHED THIS PRODUCT ON KICKSTARTER AND IT WAS FUNDED OVER 200% If you compress any amount of mass, it becomes denser. If you compress it enough, it will become so dense that light can no longer escape it—this size...

Set of 10 cubes of various materials to compare densities.   Materials come in a royal blue plastic case. Cubes are 1" (25.4 mm) Materials included: Copper (8.85 g/cc) Brass (8.4 g/cc) Steel (7.8 g/cc) Aluminum (2.7 g/cc) PVC (1.35...

½ ounce (14 g) of pure zinc metal Zinc (Zn) is element 30, add this to your periodic table ¾” wide x 5/16” thick hexagon

Radium [Ra, 88] is a radioactive element, so it isn't something you come across everyday. But decades ago, it was painted on watch hands since it naturally glows in the dark. This practice was discontinued in the 1960s, and now these...

With this future-proof table, blank boxes are arranged as placeholders for the predicted locations of undiscovered elements. When a new element is confirmed, write in its name, symbol, weight, and other properties it might have in the appropriate box. Includes...

Large size: approximately 50-80g Medium size: approximately  30-45g Small size: approximately 15-25g Photos are representative of what you will receive. Please allow for slight variations in shape and color.  Further information: Bismuth is a chemical element with the symbol Bi and atomic...

Shine a bright flashlight (like the one on your cell phone) directly onto the side of this jar of powder for a few seconds and remove it to see something amazing.  This is a new generation of phosphorescent powder that...

One - 1 ounce, 99.9% pure copper bar Copper is what we call any atom containing exactly 29 protons. It is one of the most useful chemical elements to humanity. Copper was one of the first metals discovered and used...

Lead is a chemical element with the symbol Pb (from the Latin plumbum) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low...

Wafers are thin sliced semiconductors used to manufacture microelectronics and computer components. This sample is an 8" uncut silicon wafer with integrated circuits. Each wafer contains thousands of duplicate photo-lithographed circuits. Typically this wafer would have been cut up and the...
