DIY SCI host Steve Spangler demonstrates how you can make your very own egg geode at home!

Ten years ago, deep in Montana’s remote Tom Miner Basin, Casey Anderson made a choice few would dare: instead of running from a grizzly bear den… he crawled inside. Now, in one of our boldest episodes yet, Coyote teams up with Casey to...

Metal excess defect due to excess cations occurs when extra positive ions (cations) are present in the crystal lattice, occupying interstitial sites to maintain electrical neutrality. To balance the excess positive charge, electrons are...

Imperfections in solids are irregularities or deviations from the ideal arrangement of atoms or molecules in a crystalline solid structure. These defects can occur during the crystallization process when the rate of crystal formation is...

Supralateral arcs, ice pillars and sun pillars.

Light pillars are optical phenomena that occur in extremely cold atmospheres, when flat ice crystals form close to the ground. They reflect natural and artificial light in columns that extend through the sky. This captivating spectacle...

Polaroid pictures work by using a light-sensitive film that is exposed to the incoming light of the scene you wish to capture. The film is then developed in a matter of seconds, producing a negative image. To create the final, positive...

The song name is displayed on the radio with the help of a specific communications protocol called the Radio Data System, which embeds small bits of information in FM broadcast signals. RDS allows broadcasters to send much more than just...

Discover the chemical processes occurring deep within the Earth that create beautiful crystal structures in caves. Chemistry - Reactions - Learning Points. Caves are a result of rainwater slowly carving away rock. Carbonic acid forms in...

We use a supersaturated solution of sodium ethanoate to demonstrate instant crystallisation. Sodium ethanoate is added to water and is then heated to allow all of the crystals to dissolve. When it is cooled it forms a supersaturated...

We add potassium iodide and lead(II) nitrate to the opposite sides of a Petri dish filled with water to see how quickly they diffuse. When added to the water, the chemicals spread through the dish and when they meet they react to form...

A look at caves of all shapes and sizes: how do they form? And what creates the strange stalactite and stalagmite structures that can be found inside? Earth Science - Geology - Learning Points. Caves are natural underground holes carved...
