• 00:47 The Iodine Clock Reaction!

  The iodine clock reaction is a classical chemical clock demonstration experiment to show chemical kinetics in action. It was discovered by Hans Heinrich Landolt in 1886. Two color solutions are mixed and at first there is no visible reaction. Then you'll see the solutions changing to clear or cloudy white color.
  
  The iodine is mixed with starch to make a dark blue-black color solution. Then the solution of vitamin C is added to make it clear.
  
  How does it work? Iodine has two different “oxidation states” – one where the iodine molecules have a negative charge (I-) and the other where they have no electric charge (I0) Only the iodine with no electric charge can combine with starch to make the blue-black color. Certain chemical reactions (called oxidation and reduction reactions) can make iodine shift back and forth between these two states when it is mixed with Vitamin C solution.

• 00:39 Dancing Raisins

  You'll see raisins bobbing up and down in the soda. Why does this happen? Raisins are denser than the liquid in the soda, so at first, they sink to the bottom of the glass. The carbonated soda releases carbon dioxide bubbles. When these bubbles stick to the rough surface of a raisin, the raisin is lifted because of the increase in buoyancy. When the raisin reaches the surface, the bubbles pop, and the carbon dioxide gas escapes into the air. This causes the raisin to lose buoyancy and sink. Then the process happens over and over again until the soda loose its carbon dioxide gases.
