This cube contains an incandescent light bulb. The colorless gas inside the light bulb is argon. If the bulb were instead filled with air, the tungsten filament would be rapidly oxidized when the bulb is turned on.

The Argon cube is attached to a purple ribbon that represents argon's inclusion in the noble gases group on the periodic table. Each cube is also labeled on the bottom face with the element’s name and symbol as well as the sample description presented above.

Each Element Cube is approximately 2” (5 cm) by 2” by 2”. The perfect size for convenient display! The cubes open for closer examination of the samples inside, although many samples are glued down for proper presentation.

Please note that these are handmade ornaments and it is possible that the ornament you receive will not look exactly like the one pictured in this listing. The item will be the same, but sample variations (e.g. color, shape, size) and placement may differ.

Element Cubes are a great gift for teachers, students, scientists, and collectors! Only the unique beauty of each elemental sample surpasses the educational value of this collection. These ornaments will add a special flair to any tree for Christmas, Winter Solstice, Saturnalia, or other holiday celebration.

Did you know that the element boron is responsible for the special pliability of Silly Putty? Did you know that the air we breathe is 78% nitrogen? Were you aware that some marbles are made with radioactive uranium to induce a green glow under a black light? Well, now you do. And you and your family will continue to be amazed by each Element Cube as you learn how each chemical element is used in electronics, home products, jewelry, and much more!

The Element Cube collection has just begun and will be growing very soon. Please check back for new additions!
