The tornado bottle experiment is a science experiment that demonstrates how a tornado is formed. The experiment involves creating a vortex in a bottle of water or vinegar by swirling the bottle. The vortex will create a tornado-like effect, with the water or vinegar swirling around in a funnel-shaped cloud.

Vinegar is better than water in the tornado bottle experiment because it is more viscous. This means that it is thicker and more resistant to flow than water. The increased viscosity of vinegar helps to create a stronger vortex, which results in a more powerful tornado.

In addition, vinegar is clear, so it allows you to see the vortex more easily. Water is also clear, but it can sometimes be difficult to see the vortex because of the reflections of light off the surface of the water.

For these reasons, vinegar is the better choice for the tornado bottle experiment.
