The Singing Tube is a great science demonstration used to teach students about sound waves, as the piece of metal pipe is made to magically sing. Since this demonstration requires the use of fire (a propane torch), it must be done by an adult… with a child-like enthusiasm for making science fun.

You never quite know what's going to happen on the 9News 4 O'Clock Show each Monday, but it's a good guess that something will fizz, pop, splat or explode and you'll probably learn something at the same time. Each week Steve Spangler comes up with some way to make learning about science fun. One 9News viewer writes, "Every Monday afternoon, my kids are bound to hear me yell, 'Get in here! You won't believe what Steve Spangler is doing today.' After I'm done laughing I realized that I actually learned something." Here's a look at some of our favorite Spangler Science segments from 2008.

Who can resist the temptation of swinging a pail of water over their head? This science stunt isn't just for kids as Steve Spangler proves with his swinging tray of glasses... filled with coffee. Steve has a most unusual way to mix his morning coffee. Thanks to a little help from gravity and centripetal force, a cup of coffee never tasted so good. Where's a stirring stick when you need one?

Ordinary people use standard electricity from the wall to power a light. Oh, but not you! Why use normal electricity from the wall outlet when you can make your own? Get ready to amaze everyone with this shocking display of science.

What color is black? Some people answer with a simple black while others respond with something like black is the absence of all color. Let's try for a third answer. If you have ever run out of black paint or your black pen ran dry, you probably know how to make the color black. Mix a little blue with red and yellow and green and orange and purple and you finally make the color black. Do the people who make black pens mix different colors to make black? Using a technique called chromatography, let's find out exactly what makes up the color in that black pen.
