A jerry-can filled with diesel may be explosive
if ……
A tank previously filled with gasoline but now filled
with Diesel is up to the complete evaporation of the
gasoline just as explosive and in danger of catching
fire as if filled with gasoline only. The gasoline swims
on top, those steams are explosive. As soon as the gasoline
burns the Diesel will immediately also burn.
Cockroach-killer putty:
A tube of sweetened condensed milk mixed with boric
acid and dispersed to putty is a fantastic Cockroach-killer.
Pills of the putty are glued at various places in the
camper / boat.
Cockroaches eat the putty and leave the car to find
water or shrivel.
Keep it clear from cats and dogs!
The whole procedure requires about 3 weeks to kill all
the nasty beasts.
How to keep the pest out of food-containers:
1. Method (Container must be hermetically sealed):
Place a small bag of char onto the bottom inside of
the container. This deprives the oxygen out of the air
inside the container.
2. Method:
Put some bay-leaves into the container.
Water purification for free:
Fill clear (sediment-filtered) water into clean PET bottles
and expose it to sunlight on a sun-reflecting surface for at least
6 hours. The UV-A radiants as part of the
sunbeams kill the microorganisms to a very high extend.
