SpongeBob & Friends and the Scientific Method Scenario A. Krusty Krabs Breath Mints
Mr. Krabs created a secret ingredient for a breath mint that he thinks will "cure the bad breath people get from
cating crabby patties at the Krusty Krab. He asked 100 customers with a history of bad breath to try his new
breath mint. He had fifty customers (Group A) cat a breath mint after they finished eating a crabby patty. The
other fifty (Group B) also received a breath mint after they finished the sandwich, however, it was just a regular
breath mint and did not have the secret ingredient. Both groups were told that they were getting the breath mint
that would cure their bad breath. Two hours after cating the crabby patties, thirty customers in Group A and ten
customers in Group B reported having better breath than they normally had after cating crabby patties.
