Homemade jet engine which raises flame a little bit of feeling

I do not know exactly what to use, but it is an experimental movie of people who made jet engines by themselves. Some are performing homogeneously because they are homemade, but everyone is blowing up a beautiful flame.

Details are as below.
It seems to be quite hot, but it is working properly.

I have a hard time putting a fire on fire, but in the end I have a solid fire.

It seems that it was made from tin can and frying oil, and operation is a little dangerous.
