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 list

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

+ Stop Light rxn

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 X

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 5

Red Cabbage dye...demo also...
