Snow to Boiling
Drip-pan or Reflector? What is the purpose of the under-element pans on the stove? In the spirit of science, and wanting the snow to go away, we will run some tests to see how long it takes to go from snow to boiling with both old and new “drip pans”.
Breast Size Measurement via Archimedes’ Principle
Breasts come in a wide variety of sizes, and due to their shape, are difficult to accurately measure to determine their actual sizes. In this study we will use Archimedes’ Principle, which uses the displacement of water, to measure the sizes of both natural breasts and augmented breasts.

Cooling Ability of Fresh Ice vs. Melty Ice
Initial observation:
When making mixed drinks and reusing ice, the shaker seems to become much colder than when using ice fresh out of the freezer.

Times when you didn’t realize the fleetingness of existence and proceeded with your life, careless that the world around you may forever change. In particular, pertinent to this day and this post, I keep kicking myself for passing up a chance to see Douglas Adams when he came to speak at my university. That was April 25, 2001. He died May 11, 2001 of a heart attack. I had thought to myself, that surely, I would have a chance to hear this great man again, and that missing this one university event wouldn’t matter too much to me.
So. To honor the anniversary of the birth of Douglas Adams, our first science experiment regards, in part, the thermal properties of a cup of tea.
