How do you measure a certain amount of time creatively?

Question

In myt science class we have to measure 20 seconds and who ever comes up with the most creative way wins. What I want is a very good idea!

Answer 1

Candle clocks provide a way to tell time. The sides of a candle were marked to indicate the passage of time as it burned. King Alfred the Great of England is credited with inventing the graduated candle in the late 9th century to divide his day into equal periods of study, prayer, royal duties and rest. During the Sung Dynasty in China (960-1279), calibrated candles and sticks of incense measured time. For example, one incense stick had six threads at regular intervals with weights on either end that draped over it. As the incense burned, the threads burned one by one and the weights dropped to a sounding plate below, indicating a time.

Try using a birthday candle. Record how far down it burns in twenty seconds. Mark another birthday candle at the same point. Time the second candle to see how close the candle has burned to the mark you made predicting where the flame would be in twenty seconds.

Music.

Light a candle in an upturned jar, it will use all the oxygen in the jar, depending on the size, will depend how long it lasts....you figure that bit out.

Put a whole in a container, fluid rushes in at a set rate....when the container sinks....you have your result.

wind string around a whieghted reel, gravity will pull on the string, spinning the reel as it falls.........set amount of string will last a set amount of time.

good luck.

We can measure such intervals by counting, jumping up and down, singing a song, doing some dance steps etc. Choose something which you are comfortable with.
