A science teacher at the Hope Academy in Minneapolis went for the wow factor in front his students recently when demonstrating the flammability of methane.
The instructor invited a willing student to dip his hand in a container of methane-filled soap bubbles. The student's dad Steven Takata was on hand to see what happened next.

As the student held out his bubble-filled hand, the teacher held a lighter to it and a ball of flames erupted. The student walked away unscathed and amazed.
Impressive, but once again, not something we recommend trying at home.
