Subliminal Messages: Do They Really Work?

Subliminal Messages: Do They Really Work? | Science Fair Projects | STEM Projects
Have you ever wondered if subliminal messages really work? This science project will explore the effects of subliminal messages on people's behavior. Participants will be exposed to messages with and without embedded messages and their responses will be observed.


The hypothesis is that persons exposed to subliminal messages will more likely respond accordingly to the information contained in the messages.

Method & Materials

You will need to record some songs with an embedded message that “Orange colored M&Ms taste better than the other colors” being repeated in the background. You will then divide the participants into two groups and have them listen to the recordings for five days. On the sixth day, the participants will be given 20 pieces of M&M each and asked to choose five out of the 20 pieces given to them.
You will need 20 boys and 20 girls age 12 who have their own stereo sound systems with CD players, or iPods (or equivalent MP3 players), an MP3 recorder/player with sufficient memory storage, 40 blank recordable CDs, and 200 pieces of each color of M&M.


The results of the experiment showed that the group exposed to the embedded message had a preference for the orange colored M&Ms compared to the other colors. There was no specific tendency towards a specific color choice for the participants in the group not exposed to the embedded message.

Why do this project?

This science project is interesting because it explores the effects of subliminal messaging, which is a controversial subject. It also provides insight into how our subconscious minds can be influenced by messages that our conscious minds may not agree with.

Also Consider

Variations of this experiment could include testing different types of messages, different age groups, or different lengths of exposure.
