Don´t try this at home

We had our family meeting in Sääksmäki with about 70 participants. One of my distant relatives belongs to the local voluntary fire brigade. They taught us how to use the foam extinguisher.
They also showed to us what happens, if You try to put out burning cooking oil in a kettle with a cup of water. This happens, so don´t do this at home.
There was also other program, but this was the most blippable and useful.
