Kitchen Oil Fire !
At the Fire Fighting Training school they would demonstrate this with
a deep fat fryer set on the fire field. An instructor would don a fire
suit and using an 8 oz. cup at the end of a 10 foot pole, toss water
onto the grease fire. The results got the attention of the students.
The water, being heavier than oil, sinks to the bottom where it
instantly becomes heated. The explosive force of the steam blows the
burning oil up and out. On the open field, it became a thirty foot
high fireball that resembled a nuclear blast. Inside the confines of a
kitchen, the fire ball hits the ceiling and fills the entire room.
Also, do not throw sugar or flour on a grease fire. One cup creates
the explosive force of two sticks of dynamite.
