Students learn to make bomb via YouTube, hide it under teacher's chair

A group of Class 12 students has been suspended for a week after allegedly setting off a firecracker-like bomb under their female science teacher's chair as a prank. Reports suggest the students learned to make the explosive by watching YouTube tutorials. Fortunately, the teacher was unharmed in the incident. According to TOI, the event occurred as retaliation after the students were scolded by the teacher. One student placed the device under her chair, while another detonated it remotely, causing an explosion.
