Additional materials
Containers that don’t cost anything and otherwise end up in the trash:
Two or three transparent, clean jelly or jam jars with lids (called glass jars with
lids in the manual)
Plastic bowl or container like the ones ice cream or ground beef come in (called
basins in the manual)
Small, clean glass bottles
Items that can be found in the household or easily obtained in the supermarket:
Aluminum foil, paper towels, tealight candle, coee lter (round lter or lter
bags), cotton pads or balls, matches
Demineralized (distilled) water, sodium bicarbonate (like Arm & Hammer®
baking soda)
White vinegar (wine vinegar)
From the drug store or pharmacy:
Hydrogen peroxide (100 mL of 3% aqueous solution)
This substance is needed starting in Chapter 8 and should be given to the
experimenter only as required.
Materials that are only needed in isolated cases (e.g., nails or paperclips), will be listed
for the respective experiment.
Cleaning the containers
In chemistry, cleanliness is an essential prerequisite for the success of the
experiments, since contaminants can trigger undesired secondary reactions. So make
it a habit right from the beginning to carefully clean the used containers when an
experiment is completed.
In most cases, cold water and a test tube brush are enough. If that doesn’t do the
trick, try warm water and a little dish-washing detergent. That will help especially
with greasy or oily grime. Then rinse thoroughly!
Two tips:
Lime residues — white lms after experiments with lime water — disappear after
treatment with household vinegar.
Berlin blue (or Prussian blue) softens alkaline detergents. In both cases, rinse well
afterward, of course.
