Description:

An unlisted answer video to a listed question video, from Veritasium, a science and engineering web show with over 2 million YouTube subscribers.

Here is the original Buoyancy Quiz video that this video refers to.

In the original video it is shown that a golf ball is denser than detergent (it also happens to be denser than pure water). A golf ball however is less dense than a saturated salt solution (in the video, the golf ball floats but with most of it below the surface). Question: If you pour the detergent on top of the golf ball in the salt solution, what will happen to the golf ball? Will it stay, go down, or go up?
