Solution to Chemical Mystery #10: Out of the Blue!
In Chemical Mystery #10, plastic straws are observed to “magically” change color when waved in the air. Check out the explanation and the video.

In this simple trick, colors are made to "magically" appear and disappear on a straw. This science experiment is very easy to do...if you know your chemistry!
You probably know what happens when you place dry ice in water. Do you know what happens when dry ice is placed in acetone or glycerin? Read this and find out!
Solution to Chemical Mystery #8, and...a challenge!
In this blog post, I'll discuss how I've expanded my use of model kits within my chemistry class to help explore a variety of topics with my students.
Tom Kuntzleman loves to share chemical mysteries and that inspired me to create a list of mysteries that are appropriate for the main topics covered in IB Chemistry. In this blog post I'd like to share some detail about how I modified the mystery of the burning water.
It all started with a class my son and I took together at Marc Adams School of Woodworking (link is external). To make a long story short, we started on a Saturday morning with nothing and left Sunday afternoon with a custom built longboard. (Think skateboard but...well...longer).
In Chemical Mystery #5, I used chemistry to give the illusion that water can be lit on fire. Here is the solution to that mystery.

Conducting experiments with liquid nitrogen experiments is a sure-fire way to energize many chemistry lessons. Check out the Misbehaving Balloon demo!
