Float, sink, flink!

In this lesson, students will learn to make things flink, meaning they neither float to the top nor sink to the bottom of a fluid. They will discover that whether an object floats or sinks depends not only on the properties of the object itself, but also on the properties of the fluid (either gas or liquid) in which it is situated.
