Parents ill over milk experiment

SMITHFIELD, N.C. -- A high school teacher was suspended for a classroom experiment that caused several students to vomit after drinking large amounts of milk.

Jeff Ferguson, a chemistry and physics teacher at Smithfield-Selma High School, organized the experiment last week to test the body's ability to neutralize acids in milk.

It was intended to show the body can handle only so much before a natural reaction occurs and the person vomits. Out of 42 students in two classes, at least five did just that.

Students were not required to participate in the experiment.
