  Home Experiment: Stacking Liquids
  
  An easy home experiment; create a tower of liquids. The liquids near the bottom are more dense while the liquids on top are less dense. This can also be used to determine the relative density of solid objects. Place them in the container and see where they float.www.thirstforscience.comMusic: Kevin MacLeod

  Chemiluminescence: Luminol
  
  Chemiluminescence of luminol. Two solutions are combined, the first solution contains luminol and sodium hydroxide. The second solution is 0.03% Hydrogen peroxide and potassium ferricyanide. The luminol and the hydrogen peroxide react to cause the chemiluminescence. The iron in potassium ferricyanide is a catalyst for the reaction.This is also used by crime scene investigators. A solution of hydrogen peroxide and luminol is placed into a spray bottle. When the solution comes into contact with ...

  Underwater Fireworks: Sparklers
  
  Sparklers contain oxidizers. As a result, they are able to burn even when they are placed into an environment that does not have any oxygen.Do NOT try this at home. This should only be attempted by properly trained personnel.It also ruined a graduated cylinder :(.Subscribe for more!www.thirstforscience.comMusic: Kevin MacLeod

  "Cool" Reaction: Barium Hydroxide Octahydrate an...
  
  The reaction between ammonium thiocyanate and barium hydroxide octahydrate is endothermic. It absorbs heat from the surroundings. As a result, the temperature of this reaction will drop quickly. This causes the beaker used to freeze to the wooden board. In this video, the beaker was able to hold approximately 9kg.http://www.thirstforscience.comMusic: Kevin MacLeod

  Van de Graaff
  
  This is a collection of experiments using a Van de Graaff generator. The generator uses a belt and two rollers to build up a charge in the dome on top. The electrons will jump from the dome to reach a grounded object. Since like charges repel one another, objects placed on top of the dome will become charged and then be repelled. This is the same machine sometimes used to make someone's hair stand up in classrooms or in science centers.

  Elephant's Toothpaste
  
  A classic chemistry demonstration, also known as Old Foamy.Hydrogen peroxide is decomposed to form oxygen gas and water. When potassium iodide is added as a catalyst, the oxygen forms bubbles and creates a large volume of foam.2H2O2 --> O2 + 2H2O

  Home Experiment: Film Canister Rockets
  
  A simple rocket made from a film canister or old pill bottle. Use alka-seltzer tablets and water or baking soda and vinegar.It would be a good idea to wear goggles as you only get one set of eyes.www.thirstforscience.com

  Potassium Chlorate and Sugar
  
  A sugar cube is added to molten potassium chlorate.Potassium chlorate is a strong oxidizer. When sugar is added, it is oxidized in a violent reaction.DO NOT TRY THIS AT HOME!www.thirstforscience.com

  Conservation of Mass
  
  In a chemical reaction, matter cannot be created or destroyed. The total mass of the reactants will always equal the total mass of the products in a closed system. A simple demonstration of this concept. Reactants and products are weighed.Lead Nitrate + Potassium Iodide --> Potassium Nitrate + Lead IodidePb(NO3)2 (aq) + 2KI (aq) --> 2KNO3 (aq) + PbI2 (s)www.thirstforscience.com

  Dehydration of Sugar
  
  Dehydration of Sugar using Sulfuric AcidSulfuric acid is added to sucrose (table sugar). The acid dehydrates the sugar and results in a large tower of carbon. Water is also released in the form of steam. C12H22O11 --> 12C + 11H2Owww.thirstforscience.com
