Chemistry: Creating a Better Future
2014 Sam and Marilyn Fox Atlas Week
2:00 - 5:00 p.m.
Busch Student Center 253 B
Sponsored By: Chemistry Club
Undergraduates of the SLU chemistry club will be performing several demos, led by Saketh Javvaji. Fire in a Bottle: Place an alcohol fuel in a glass bottle and ignite the fuel to produce an internal, colorful flame. CD Bubble: Melting a CD, so that the plastic is extremely malleable and blowing a molten-plastic, sturdy bubble. Wire through Ice: Running a thin wire through a block of ice. The ice will refreeze so that the wire will be in the middle of the ice block. Reigniting the vapor trail of a candle: Extinguish a candle flame, which releases a vapor trail for the wick. Reignite that vapor trail will cause the flame to follow the trail back to the wick, relighting the candle. Boiling water in a paper bag: Fill a paper bag with water over a flame. The water prevents the paper bag from igniting, but the water can still boil in the bag. Elephant Toothpaste: Mixing hydrogen peroxide into soapy water. A catalyst is added to break down hydrogen peroxide into hydrogen and oxygen. The large amount of oxygen produced will be trapped within the soap bubbles and expand into a foam like substance.
