In the Living Areas
To investigate these areas, you will need a draft detector.

QUICKIE EXPERIMENT “A”
Making a Draft Detector
Cut out a piece of clear plastic food wrap about 5” x
10”. Tape the 5” end to a short stick so the long end
hangs freely. For the stick, you could use a pencil or
ruler (but a baseball bat probably wouldn’t be a good
idea).
That’s your draft detector. Notice that even when
you blow ever so lightly, the plastic detects the
movement of air.
