Why is it advisable not to touch a canvas tent from inside when it is raining
Answers
Explanation:
When you touch wet canvas, surface tension will draw water to your finger. There will be a “wicking” action then that will draw water through the canvas in response to your drawing water away from the canvas. When you take your finger away, this wicking will stop. However, the drop left behind where you touched, like any irregular point on an overhead surface, will draw condensation from inside the tent if it is humid. Since it usually is humid when it is raining, the condensation will build until you get a drop, but not all of it falls. What is left will still draw condensation more than the rest of the inside tent surface, so it will appear to leak from that point as long as the humidity is high.
