Medifoam

Medifoam is a foam that was invented by doctors in 2034 for UNSC patients with bullet wounds. The foam could fill in a bullet wound like a scab and even pull the bullet out. The foam would work with the body and fill in blood vessels, bones, and muscle with imations until the wound started to heal and replace it, the foam would dissolve into red and white blood cells making the process even quicker. Once the foam was set it was 97% bulletproof.. This foam was then adopted by the UNSC in 2038. Ever since then it has been in use for Spartan armor and by medical centers.
