Experiment (100x slower)
The researchers needed to be able to change a cat's lapping speed in order to test their theory. So they developed a robotic version of a
cat's tongue -- a mechanical column with a 1-inch glass disk at the tip.
This device allowed the researchers to study the liquid column for different lapping speeds using a high-speed digital camera.
