  • This video demostrates using a laser pointer in air and water to demonstrate that light travels in straight lines.
    Please conduct a risk assessment before using a laser and in England I recommend checking CLEAPPS www.cleapss.org.uk/ for advice on laser safety in schools.
    (sorry for slightly dodgy audio)
