Caffeine Test

Have you ever tasted something that says it's decaf but tastes too good to be completely caffeine free? Soon, you'll be able to check for sure.

Researchers at Washington University School of Medicine have created a "dipstick" that changes color when it finds caffeine. The test contains an antibody that is resistant to high temperatures so it can be used on coffee or soda.

Researchers say this test will be fun for the curious but important to people who need to avoid caffeine for medical reasons. We'll let you know when it becomes available to the public.
