The Questacon Ooze Tube is simple to use but can be a great introduction to some complex scientific concepts including fluid dynamics and gravity.
Just turn the tube upside down and watch the infinite different ways in which the blue ooze flows from the top of the tube to the bottom while at the same time air bubbles strain to reach the top.
The ooze in this tube is what is called a highly viscous substance. The more viscous a substance is the more friction there is between the fluid’s particles and so the more slowly it flows. Other highly viscous fluids include honey, peanut butter and glass!
