The first test with complete alchohol burns the paper because the heat, temperature, is over the burning point of paper 451F and so the paper simpley burns. The more exciting part is when you mix alchohol with water and ask for more money. The paper refuses to burn because the water keeps the tempature under the burning point and so only the alchohol burns, making the dollar dry.

 SUPER BOUNCY BALLS! WAY 1 (There are two ways I found on the internet...I propose trying both beforehand and see which produces the more bouncier, longer lasting, and better looking ball. Survival of the fittest!) __Equipment:__ A lot of Water Glass (Sodium Silicate) for the class...4 teaspoons per bouncy ball 2 beakers More Ethan...1 teaspoon per bouncy ball Popsicle sticks...Stirring stick? Gloves for the kids! Food Coloring (optional but adds more fun!) http://www.instructables.com/id/Make-a-Super-Bouncy-Ball

SUPER BOUNCY BALLS! WAY 2 Borax Cornstarch White Glue, blue glue, or clear glue (Translucent ball?) Warm Water Food coloring (optional but adds more fun!) measuring spoons (Or naked eye measurements is more likely) Spoon...Stirring stick? 2 cups to mix between Plastic Baggies Time (as a measurement i.e. a clock) []

The polymers in this expirement bond together. The polyvinyl acetate links itself when reacting with borax. Polymers are molecules made up of repeating chemical units. (Anne Helmenstine) || Solution colors will amaze the middle schoolers as I change the color of the liquid into another color, making it look like a totally different liquid. Equipment: http://www.union.edu/academic_depts/chemistry/faculty/fox/Chemical%20Demonstrations/docs/72%20Wine%20to%20Water.pdf **EGGSPLOSION!** Who doesn't like seeing things explode? With the use of some magnesium strips and hydrochloric acid, the reaction of these two result in the products of MgCl2 and H2. The hydrogen gas is stored into the egg's hallow shell and is placed upon the erlenmeyer flask ready to be blown up. Opening the tape that releases the hydrogen gas will be when an ignited stick will be thrust above the hallow egg above the hole where the hydrogen gas is zooming out. Within milliseconds, the egg explodes into numerous broken pieces and creating a loud boom. Roaring applause follows. __Equipment/Materials:__ Links- media type="youtube" key="9ogPgzGK7BA" height="344" width="425" http://74.125.95.132/search?q=cache:tdxPS-Gmq1wJ:www.juniata.edu/services/ScienceInMotion/chem/standardslabs/01,%252002,%2520%2619%2520-%2520DEMOS.doc+eggsplosion+chemistry+demo&cd=1&hl=en&ct=clnk&gl=us&client=firefox-a || Dry ice is added to a bucket of water. A soapy cloth is drawn across the lip of the bucket to create a soap film sheet. This gradually inflates into a misty crystal ball that undulates gracefully to the air currents in the room. Materials needed: A supersaturated solution of sodium acetate trihydride will crystallize when touching a solid; these solutions are extremely volatile. __//Materials needed://__ Sodium acetate trihydride Distilled water ** [|http://www.youtube.com/watch?v=uy6eKm8IRdI]

This reaction is known as an "oscillating reaction" because it does just that: it changes from a colorless solution to an amber solution, quickly to a deep blue solution, and then all over again. //__Materials needed:__// Hydrogen peroxide, ca 12% Potassium iodate in an aqueous solution of sulfuric acid Aqueous solution of malonic acid, manganese (II) sulfate, and starch 1 beaker between 500 mL and 2L in size 2-inch stirring bar Stir plate [] ** || [] 50-100 ml of 30% hydrogen peroxide (H2O2) solution, saturated potassium iodide (KI) solution, liquid dishwashing detergent, food coloring, 500 mL graduated cylinder, splint (optional)

Anti-Gravity Water [] || [] __Equipment__ This demonstration shows a decomposition of hydrogen peroxide. Manganese dioxide is the catalyst during this decomposition rnx. 2 H2O2 (aq) O2 (g) + 2 H2O(l) **Disappearing Ink** []
 * = Zainub Ghouse ||= **Genie in the Bottle** []
 * 2 grams of manganese dioxide (MnO2)
 * rubber stopper
 * 100mL of 30% hydrogen peroxide
 * flask
 * aluminum foil

Disappearing ink is a dark blue water-based solution. When it is squirted on clothing or other materials, it disappears. The colorless wet spot is left which evaporates slowly. This is made by dissolving a small amount of thymolphthalein in ethly alcohol with a dilution of water. Adding sodium hydroxide solution gives it the blue color. The change in pH cause the color to fade sodium hydroxide reacts with carbon dioxide. In result, sodium carbonate is formed. 2 NaOH + CO2 → Na2CO3 + H2O __Equipment__
 * thymolphthalein
 * ethyl alcohol (rubbing alcohol, 70% solution)
 * sodium hydroxide solution 3M NaOH
 * 5 oz plastic cup or 150 mL beaker for mixing 'ink'
 * 4 oz bottle for storing 'ink'
 * cloth to test 'ink'

 * = Dipesh Mehta ||= ICE ON FIRE []

__Equipment__
 * 5 Glass "ice" Cubes
 * Ethanol
 * 90% Isoprophyl Rubbing Alcohol
 * Boric Acid for Green flame
 * Alternative for "ice" cubes: 75% alcohol with 25% water mixture frozen

The "liquid ice" will use the alcohol vapor fumes to ignite and with the addition of some boric acid to the substance, a green flame will ignite over the "ice" providing a shock to the audience as water as it would seem can not get catch fire.

Chemical Fires!!!! []

Add a few drops of glycerin to a few crystals of potassium permanganate. Accelerate the reaction by adding a couple of drops of water. Soak a tissue with acetone to make it more flammable. Draw sulfuric acid into a glass pipette. Dip the pipette into potassium permanganate so that the tip of the pipette is coated with a few crystals. Dispense the sulfuric acid onto the tissue. The potassium permangante and sulfuric acid mix to produce manganese heptoxide and fire. Mix a small amount of sodium chlorate and sugar. Initiate the reaction by adding a few drops of sulfuric acid.

__Description__: First I would take 2 clear cups, 1 with polyurethane A and the other with polyurethane B in equal amounts. Then I would mix the two together in the cup and the foam will expand. Then I would take two additional cups, again with polyurethane A and B in equal amounts. I would mix them together and pour them into a rubber glove. The foam will expand inside the glove. Then I would take 2 cups for a third time filled with polyurethane A and B, mix them in one cup, and then slowly pour it into a bowl. The foam will eventually harden while it is being poured.

 * The Jumping Flame**

__Description__: Pour 250 mL of 3% hydrogen peroxide into the jar containing the yeast, and 250 mL of vinegar into the jar woth the baking soda. Stir each mixture. Light both splints. Blow out the flame of one splint, leaving a glowing end. Simultaneosly, insert the still burning splint into the cylinder that contains the carbon dioxide and the glowing splint into the cylinder that contains oxygen. The flame will go out in the carbon dioxide, while the glowing splint will ignite in the oxygen so the flame will appear to "jump" from one splint to the other.

__Materials__: Graduated cylinders or hydrometer jars, 1000-ml, 2 Scoop Baking Soda, sodium bicarbonate, NaHCO3, a scoopful Dry Yeast White Vinegar or 5% acetic acid solution, 250 ml Long Stirring Rods, 2 Hydrogen Peroxide, 3%, H2O2, 250 ml Long Wooden Splints Butane Lighter

 * = Anna Pamula ||= **Slime**


 * Materials:**
 * 3 eggs
 * 3 - 400 mL beakers
 * 225 mL water
 * 225 mL of 3 M hydrochloric acid (You may substitute vinegar for the hydrochloric acid)
 * 60 g of sodium chloride dissolved in 225 mL water (salt water)
 * Long pair of tongs or a spoon

Fill the beakers with each of the 3 fluids. Draw faces on the eggs to personalize them. Have the eggs ready to be placed into the liquids. Tell the first egg to float. Using the tongs or spoon, put the egg in the salt water. It will float. (If it doesn't, add a little more salt) Next, tell the second egg to swim. Put this egg in the hydrochloric acid. It will swim to the top while creating bubbles and rolling around. Last, tell the 3rd egg to dive. When put in the water, it will sink to the bottom.
