Dory believes that fish that eat food exposed to
microwaves will become smarter and would be able to
swim through the reef faster. She decides to perform an
experiment by placing fish food in a microwave for 20
seconds. She has the fish swim through the reef and
records the time it takes for each one to make it to the
end. She feeds the special food to 10 fish and gives
regular food to 10 others. After 1 week, she has the fish
swim through the reef again and records the times for each.
