Density differences cause objects to “float” in liquids that are already stacked on top of each other.
With this science-magic trick, you’ll put a new spin on our famous Density Column demonstration. First, you’ll discover how to stack nine layers of liquids on top of each other. That alone looks really cool, but then you take it up a notch by making different solid objects “float” in the middle of all those cool looking stacked liquids. You’ll surprise yourself and your friends with what you can do with the 9-Layer Density Tower. Continue reading
Use this popular, simple exercise to introduce some levity into the classroom and as an opportunity to demonstrate the importance of careful observations. Continue reading
Here’s STAO’s own Otto Wevers using his fascination with cycling to conduct an experiment to the test the buoyancy of his fat tire bike.
Our science guy Steve Spangler brought in extra help today to set-up today’s experiments with soda, bowling balls and lots of water. Continue reading
This demonstration reviews the concept of density. It examines why certain objects float or sink in water and highlights some interesting information about cola versus diet cola soft drinks.
