This experiment lets you test your sense of smell. You will need some yoghurt pots, an old pair of tights and some elastic bands.
1) Place a different substance into each pot and seal it with the tights and elastic bands. Substances to use could include chocolate, lemon peel, vinegar, onion, cheese, soap and herbs.
2) Label each pot so that you know what is in each one (use a code so that other people do not know - keep a record of the code).
3) Now ask your friends to identify what is in each pot using their sense of smell alone. Make a table of your results.
Which of your friends has the best sense of smell?
Whose sense of smell is the poorest?
Can we smell something that is under water? Devise your own experiment to find out.
