There have been reports for over a century of people finding what the Germans call sternenrotz (which literally means "star snot") in conjunction with meteors falling from the sky. It's usually clear or yellowish, smells awful and disintegrates after being handled. Despite being described thoroughly in numerous newspaper and police accounts for over 150 years, no one has ever really been able to study it in depth because the substance falls apart too quickly to allow for a sample to be obtained.
