Seminole High School locked down after student brings mercury-filled thermometer to class for chemistry project

Boca Ciega, Florida -- A chemistry project caused a big problem at Pinellas' Seminole High School Tuesday morning.

The Pinellas County Sheriff's Office says students were given an assignment to bring in a substance from the Periodic Table of Elements.

One student brought in mercury -- contained within a thermometer -- and the school went into lockdown.

Deputies say the thermometer was discovered as the substances were checked before going through the school.

No one was put in harm's way, but a hazmat crew was there as a precaution.

Pinellas County Schools tell 10 News the students were told not to bring certain toxic elements from the periodic table, mercury included.
