Department Dinner Demo Night!

The Chemistry Department's first ever "Demo Night" themed dinner gathering included some of the professors' and students' favorite demonstrations.  Students Brayton and Caroline performed a luminol demonstration, and Olivia prepared coffee using a special pour-over method.  Dr. Kroll prepared a number of treats demonstrating molecular gastronomy.  Dr. Hammond amazed the crowd with his balloon creations and then shrinking and expanding them in liquid nitrogen.  Dr. Stan performed a number of demos including the Elephant Tooth paste (lots of bubbles, lots of mess, lots of fun).  Dr. King wrapped the evening up with some fire demos including the hydrogen balloon finale (of course).

Dr. Kroll, having way too much fun with his food!

Coffee Fun!  (yes, this was brand new glassware)


  1. How does one make the elephant toothpaste reaction bigger

  3. Well, quantity and rate both affect the appearance of this one. You can increase the amount of hydrogen peroxide and/or potassium iodide. Mixing quick is helpful. Also, the narrower the cylinder, the more dramatically it shoots out the top.
