What's that Smell?
Before the party, prepare a number of small muslin bag which contains various pungent smelling goods -e.g. coffee, lavender, curry powder, sage, lemon, thyme and so on – and put them on a try. Ak each guest to smell each little bag and write down what they think it contains. It will be found that after the first two have been identified fairly easily, the sense of smell will become numb and it will be exceedingly difficult to identify the remainder. Give a small prize to the competitor who correctly names the highest number of “smells”.
