Introduction, Why present?

In 1825, Michael Faraday started a "Royal Institution Christmas Lectures" in order to present scientific concepts to the local community. These lectures were geared toward both young and old.

Demo 1

Start with a bang! CaC2 + H2O --> C2H2 (g) + Ca(OH)2

a) do in large beaker (Brad)
b) do in small bottle (Chris)
c) do in larger bottle (Steve)
d) larger (Chris pretends...)

Demo 2

String in a box...questions/theories... (Brad)

Demo 3

Chris

Magic Jug
Requires Six clear glasses and a clear jug.
A jug of Ammonium Iron 3 sulfate
Glass one - Potassium thiocyanate
Glass two - Barium chloride
Glass three - Potassium ferrocyanide
Glass four - Tannic Acid
Glass five - L-tartaric acid
Glass six - Sodium bisulfite
Traffic Light Reaction
Two beakers of water.
Glucose in the larger (~700 ml warm water)
NaOH in the smaller (~250 ml cold water)
Indigo carmine in the larger beaker (turns blue)
Combine the two beakers and get green for a moment, then red, orange, yellow.
Addition of oxygen will turn the reaction back to red.

Demo 4

Steve Universal indicator in flat panel "canvas'

  • add HCl to make it turn red (Monmouth)
  • add NaOH to make it turn purple (Knox)
  • add CO2 when Red to have it change.

Demo 5

LED lights/PDA/Lasers and Fog machine (all)

Demo 6

Float Sink game...

pop cans
bowling balls

Demo 7

Magnet and Cu tubing...(Steve)

Demo 8

End with a bang...Methanol pop bottles...with cups of confetti on top...
