A great way for the young chemists to start experimenting and finding out about different
liquids etc by testing with Ph test papers to see whether they are acids, neutral
or alkali’s. Use the box as your test tube rack, the box contains 6 test tubes, 6
pipettes, 3 Litmus books containing 60 test papers that can be increased to 120 tests.
Instructions, notes on the states of matter: solids, liquids and gases. You supply
the household materials for testing. The photo shows examples.
