A class of apprehensive students in Mexico conducted the experiment under teacher, Ricardo Torres Martinez, supervision.
If faced by a bull sprinting towards you, very few people would think the best reaction would be to do absolutely nothing.
Yet, as this unusual classroom demonstration shows, bulls will only attack humans if they are provoked.
Teacher Ricardo Torres Martinez lined up his pupils in rows in a bullring in Apodaca, north-east Mexico, before releasing the animal.
As the young bull is let out into the enclosure the youths wait nervously to see what will happen next.
The animal runs around and in between the students in an attempt to find a way out of the ring.
