Discovery Word Activities

Only four shows were given at Discovery World since NCW occured during the week that the local schools had a short week due to teacher conventions. The shows were presented by students from Carroll College and UWM. The participants were -

Carroll College	UW-Milwaukee
Taulant Bacaj Krystal Bauz Cara Casper Mary Froemming Kevin Raduka	Sr. Mary Rose Attu Darin Evans Kristen Murphy Chris Oberle Vince Puppero Tom Sorensen

A list of the demonstrations performed and pictures are shown below.

Note: Not all demonstrations were performed by all demonstrators. Genie in a Bottle The catalytic decomposition of H2O2 to evolve heat resulting in a steam cloud comming from the bottle. Disappearing Ink When sprayed on white fabric, the ink will disappear after a few seconds. Bleaching Fabric Whitening actionof commercially available chlorine bleach. Iodine Solution Iodine solution chemically changed from brown/red to blue (once starch is added) to colorless (with the addition of thiosulfate. Styrofoam Race Using two large beakers, one with water and the other with acetone, the participants try to fill the beakers with styrofoam packing "popcorn". The popcorn disolves in the acetone. Light Bulbs The activation of fluorescent light bulbs with static electricity. Old Fashioned Drain Cleaner A mixture of baking soda and vinegar can be used as an alternative to Drain-O. Glowing Gummy Bear A gummy bear candy is oxidized rapidly in a test tube to generate a large amount of heat so that the candy glows. CO2 Shower Soap encapsulates carbon dioxide gas into a bubble. Since the CO2 bubble is more dense than air, it will sink to the ground. Elephant Toothpaste The decomposition of H2O2 evolves oxygen, which becomes trapped in the soap and forms a frothy mess. Halloween Colors The catalytic decomposition of Hydrogen Peroxide (H2O2) via a color change. In a iron nitrate solution, the addition of hydrogen peroxide results in a color change from orange to black back to orange. Methanol Cannon Sparking vaporized methanol to blow out a stopper on a bottle. Electric Pickle The heating and glowing of a whole pickle when an electric current is passed thfough it. Burning Money The difference of burning of paper with pure ethanol and burning paper (money) with a ethanol-water solution. Whoosher Bottle The burning of methonal in a large carboy to create a whooshing sound. Hydrogen Ballons The ignition of ballons inflated with hydrogen gas.

Students from Phillips Elementary enjoying the show. Krystal Bauz releases the genie. Darin Evans demonstrates the bleaching of fabric while Vince Puppero looks on. Tom Sorensen and Sr. Mary Rose Attu clean iodine from fabric. Kevin Raduka, Cara Casper and Taulant Bacaj officiate the styrofoam race. Cara Casper and mary Froemming with Taulant Bacaj and Kevin Raduca looking on cause fluorecsent lamps to glow. Carroll students demonstrate the oxidation of gummybear candy. Tom Sorensen and Sr. Mary Rost Attu make drain cleaner. Tom Sorensen puts out a candle under the CO2 shower. Students from Honeycreek Elementary enjoy a CO2 shower. Kristen Murphy conjures the halloween colors. Krystal Bauz makes elephant toohpaste. Cara Casper tries to burn some money. Chris Oberle ignites some flash cotton. Carroll students set off a hydrogen filled ballonn for a finale.
