Density Column

The densities of different liquids can be easily demonstrated by making a density column.  Steve Spangler has a splendid density column demo that I decided to make on a much larger scale.  Instead of using a graduated cylinder I decided to use a fluorescent light bulb tube guard. To seal one end of the tube I used duct tape and Goop so that no liquid would leak out.  Once the tube is ready, it's just a a simple matter of pouring the liquids into the tube according to their densities. Check out the video for the results and for some additional tips.
