 '''materials:'''
 - Petri dish
 - Hot glue/ glue gun
 - 2 cables with 2 contacts each
 - Crocodile cable
 - mud
 - water
 - Voltmeter
 - Agar- Agar Powder

 '''Experiment'''
-.	Mix agar-agar powder with water which will later be placed in the middle of the Petri
-        dish.
-	--> allow to set
-.	Glue both cables with contacts on opposite sides of the Petri dish with a glue gun. (pic1)
-	--> Make sure that the glue does not come into contact with the end of the cable.
-.	Put the agar-agar, which has become solid in the meantime, in the middle of the petri dish, so that it will
-        later become the connecting piece between the two sides of the petri dish. (pic2)
-.	Fix the agar-agar in the middle with the help of the glue.
-	The glue should be applied thickly over the entire middle of the dish so that a kind of wall is created
-        between the two cables.(pic3)
-        --> Important: '''do not leave any gaps''' when glueing, otherwise the experiment will not work properly.
-.	Then pour water onto one side of the bowl and make sure that the contact of the cable is covered.
-        --> Now do the same on the opposite side with the previously collected mud.
-        --> Again: Make sure that the water and the mud do not mix. (pic4)
-.	Adapters can now be attached to the cables, which are connected to a voltmeter.
-.	At the end of the experiment, a voltage should be read off.(pic5)
-.	The aim of the experiment is to generate more and more voltage.
-        --> This can be done by covering the dish after the project and letting it stand. After some time, more and
-        more bacteria form in the sludge, which means that if you repeat the experiment after a week, a higher
-        voltage will be measurable.
