Science EngagementIn and Out of the
Classroom
Liquid Nitrogen Content / Context
Very cold liquid 77K (-196 C)
Boiling at room temperature
Rapid converts from a liquid to a gas
Causes rapid condensation from atmospheric water.
Science Demonstration
Liquid Nitrogen Demonstrations
Liquid nitrogen in a clear plastic bag.
Liquid nitrogen in a black plastic bag.
Liquid nitrogen in a sealed container.

Science Demonstration
Chemical Luminescence Content / Context
Same concept used in glow sticks.
Production of light from chemical reaction.
Exothermic reactionConservation of
energy through fading.
Science Demonstration
Glowing Fountain Demonstration
Combination of two liquids.
Use of atmospheric pressure.
Pressure Balancing.
Chemical Luminescent Fountain
World’s Largest Periodic Table of the Elements
Periodic Table• Sold sponsorships
for individual elements.
• Iodine• Curium• Krypton• Gold
• Installed the table in one night.
• Stayed up for one week.
• Launched the 2006 Chicago Science Expedition “2 Weeks Worth of Wow!”

Next Big Thing
Why was this impressive
The table was up for one week, and was featured in Chemical & Engineering News, and all local news outlets.
Launched city-wide science celebrations in 2007 and the 2008 Year of Science from MSI.
Check out this guy.
Atmospheric Pressure Content Context
Air pressure 14.7 lbs/in2
Counter intuitive demonstration.
Exactly the same as the luminescent fountain.
