Tide believed that part of this problem was that the package was too appealing (not found from this case study), some children believed it to be candy because of its bright and friendly color scheme, but more than just the Pod design faults this package. Tide pods use a specific polymer called ethoxylated polyethylene polyamines, this is a water soluble polymer that burst when it comes in contact with water. So once the pod touched the mouth of a child it would burst releasing chemicals into the child's mouth.
A possible solution to this problem is to create containers that are child proof. This can cause frustration with consumers who do not have young children, but as a packaging scientist these changes decisions have to be made.
