The “Magic” of the Soother Ooze Tube


Ken Byrne, Educational InnovationsBy Ken Byrne

Someone once told me that all magic is science, and all science is magic.  To me, a magic show is a series of puzzles for me to solve, trying to figure out just how they pulled off an illusion.  My favorite science demonstrations are much the same.  I love those demonstrations that make me scratch my head and ask, “Why?”

Here is one of my favorites that is easy and inexpensive.  It feels like a magic trick, but it is all science.  It simply involves rolling a cylinder down an inclined plane.  Sometimes the cylinder will roll down quickly.  Other times it will crawl down slowly. Read the rest of this entry »

From trying to figure out why two ice cubes melt at dramatically different rates to brainstorming explanations for how a sealed opaque balloon suddenly starts self-inflating, these demos engage students, assess their science skills, and emphasize the processes and habits that scientists use to inquire about the world around them.

You Said It! Density Product Reviews


You Said It! Product Reviews - Educational Innovations NewsletterWhenever we attend a science convention, we bring plenty of density demos.  They are invariably among our best showstoppers!  There is something wonderfully confounding—and compelling—about watching a (seemingly) heavy object float against our expectations, or seeing (seemingly) identical beads travel in separate directions.  This curiosity is the heart of why discrepant events are so valuable to educators.

Is it magic?  No, it’s density!
