Top 10 Amazing Chemical Reactions. Our World Chemical reactions are part of our daily lives. From cooking in the kitchen, to driving a car, these reactions are commonplace. This list is aimed at some of the more exotic and amazing reactions that most of us have not seen or experienced.
My knowledge of science is limited, so if I have made a blunder in my descriptions, please let me know so that I can correct them! Here are the top 10 amazing chemical reactions. Do not try these at home (but if you do – send us the video clips!) Sodium and Water in Chlorine Gas Sodium is a highly combustible element and the addition of water can make it explode.
Magnesium and Dry Ice Reaction Magnesium ignites easily and burns very brightly. Potassium Chlorate and Candy Reaction Potassium Chlorate is a compound containing potassium, chlorine and oxygen. When a superconductor is cooled to below its transitional temperature, it becomes diamagnetic: this is when something is repulsed from a magnetic field rather than drawn in to it. Jamie Frater.

Secret Worlds: The Universe Within View the Milky Way at 10 million light years from the Earth. Then move through space towards the Earth in successive orders of magnitude until you reach a tall oak tree just outside the buildings of the National High Magnetic Field Laboratory in Tallahassee, Florida.
After that, begin to move from the actual size of a leaf into a microscopic world that reveals leaf cell walls, the cell nucleus, chromatin, DNA and finally, into the subatomic universe of electrons and protons. Once the tutorial has completely downloaded, a set of the arrows will appear that allow the user to increase or decrease the view magnitude in Manual mode.
