How can you submit a new candy idea and get credit for it if are only fifteen?

While some companies accept unsolicited candy ideas, they generally do not offer compensation to idea submitters, regardless of age. It's important to check the specific guidelines of each company you contact before submitting an idea.

It's also worth noting that your age may be a limiting factor in participating in certain contests or submitting ideas to some companies. Some companies may have minimum age requirements for participation. In general, it's best to check with the specific company you are interested in submitting an idea to for their guidelines and requirements.
