In this short film you will see animals responding to
water droplets. These were control experiments.
After controls were filmed, DPRs were covered with a
plastic elastomer (Kwick Cast, WPI). This film shows the
response of an animal while DPRs are covered
Removing Cover This movie
shows the plastic elastomer being removed.
This movie shows the immediate response after DPRs are
uncovered. Note how the last animal ignores a piece of food and responds
to the water droplet.
