Video Demo: Sugar Goo

Thirty ml of sugar (sucrose) (C12H22O11) is mixed with 30 ml of sulfuric acid (H2SO4).  A chemical reaction takes place to produce carbon, water (H2O) and sulfur trioxide (SO3).  It's a fun chemical reaction to observe because there are dramatic changes in color, smell (make sure good ventilation is present), and temperature (so much heat is released that it melts the plastic cup).  Gases are also produced which add to the drama.

Why the different reaction rate in the plastic vs. glass containers?

I'm not sure why. Maybe the chemicals in the plastic container mixed more thoroughly.
