MILK CARTON HYGROMETER
Transcript of MILK CARTON HYGROMETER
INSTRUCTIONS TO BUILD THE MILK CARTON HYGROMETER
ANALYZE HOW IT IS THE BEST INSTRUMENT IN HELPING PREDICT THE WEATHER
Hygrometers are a simple device that are used to measure the humidity levels and the temperature of the surroundings and are widely applied to predict the weather. When it is up to it's highest it is most likely it will precipitate.
WHAT IS IT USED FOR?
The milk carton hygrometer is used for measuring the humidity in the atmosphere.
HOW IS IT USED?
Set the pointer to the far left, which represents no humidity, wet the hair and the pointer should go right. Another way is to wet the hair and set the pointer to the far right and then dry it and the pointer should go left.
THINGS YOU WILL NEED:
Empty milk carton
Large sewing needle
Glue or tape
paper or card with/Without scale
9” strands of straight hair
EVALUATE WHETER IT IS USED ALONE OR WITH ANOTHER TOOL TO PREDICT THE WEATHER
It may be used alone but the best results would come if you use it with another tool and because they must be calibrated at least once a year to ensure they provide the most accurate results as possible. Even the best and most expensive hygrometers accuracy is likely to alter over time.
BY : ASHLEY FUNES BONILLA
Get an empty quart milk carton and cut an “H” shape at the bottom end.Bend up the tabs upwards. Therefore punch holes in the center of the tabs for the pointer spindle(needle). Cut the card/paper into a square shape and tape/glue it directly under the tabs. Then attach the straw to the needle. Tape one end of the hair to the penny and use the other end to take 3 or 4 turns around the needle (or make a knot) and then tie it to the paperclip. It should leave the penny hanging about halfway down the box . TADA YOU'RE FINISHED!
