Play detective with this great little experiment kit. Use the included pH indicator paper to find some common acids and bases around your house. Simply take a leaf of paper from the pH pad and dip it into the substance you are testing - the colour the paper turns indicates the pH of the substance and whether it's an acid or a base. Test vinegar, water, milk, orange juice, toothpaste, washing liquid and much more.
Also use this kit to discover which pen wrote a "mystery" note, or forged an altered cheque, with a common forensic technique called chromatography. Included in the kit is special filter paper and instructions on how to separate inks into their component colours and pin point the source of different ink.
Age: 10 +
