The teacher instructs the student to dip his hand into a container of methane-filled soap bubbles and then holds a lighter to the student's hand.
The methane-filled bubbles briefly ignite and flames engulf the boy's hand, but they quickly put themselves out and the student is left amazed and uninjured.
"In a classic science demonstration, soap bubbles filled with methane are lit in a fireball in my son's hand," Takata wrote.
