Icebergs float in saltwater, so you might think they consist of frozen saltwater. Actually, icebergs are made of freshwater. How Icebergs Form Icebergs form on one of two ways: Make a Homemade Iceberg Freezing saltwater is one way of desalinating it to get fresh water for drinking. If you aren’t […]
Are Icebergs Made of Freshwater or Saltwater?
Fire breathing is a dramatic effect created when a person blows a spray of fuel over a flame. The result is a plume of flame jetting from the fire breather’s mouth. The effect is simple to achieve, but not so easy to do safely. Most performers use kerosene, lamp oil, […]

The transition metals are the largest group of elements on the periodic table. They got their name because English chemist Charles Bury described a transition series of elements in 1921. Bury examined the transition from an inner electron layer with 8 electrons to a layer with 18 electrons and from […]

The nitrogen triiodide chemistry demonstration is a dramatic explosive reaction that produces sound and colored vapor. Crystals of iodine react with concentrated ammonia to precipitate nitrogen triiodide (NI3). The NI3 is then filtered out. When dry, the compound is so unstable that the slightest contact causes it to decompose into […]
