Article: This can be expressed as the ratio of grams of water vapor to the number of kilograms of dry air. This is called the "actual mixing" ratio. This data can be obtained online as measured from instruments such as a microwave water radiometer. Measuring the water vapor in the air is not something that can be done with household items. This is the point at which the air would be saturated with moisture and is called the saturation mixing ratio. The amount of water vapor the air can hold is dependent upon the temperature of the air. Tables are available online that will tell you the capacity of water vapor at a specific temperature.  The higher the temperature, the higher the water vapor capacity. To determine how much water vapor the air can hold at a certain temperature, reference the table at https://brownell.co.uk/datasheets/basics_humidity.pdf. This simple calculation produces the relative humidity. Thus, if the air currently holds 20 grams of water per kilogram of dry air and can hold 40 grams of water per kilogram of dry air, the relative humidity would be 20/40, or 50 percent.
Question: What is a summary of what this article is about?
Determine how much water vapor is in the air. Determine how much water vapor the air can hold. Divide the actual mixing ratio by the saturation mixing ratio.

Problem: Article: Wasps are very territorial creatures, and they won't build a nest if they think there is another colony living nearby. Plus, the wasps will leave if they think that another colony has moved into their neighborhood. If the colony moves further from your home, the wasps in your house will go with it.

This will give it somewhat of a “nest” look. Once you've crumpled it, open it back up and put your filled plastic bag inside. Use your twine to hang it near the existing nest. It needs to be close enough that the existing wasps will notice it. Close the door to the room that has wasps in it. Leave the window open so that the wasp can get out. They will leave and travel with their colony.
Summary: Gather the materials for your fake nest. Fill your plastic bag with shredded paper. Hang your nest. Leave the wasp with the window open.

INPUT ARTICLE: Article: You can use an old face wash bottle, a mason jar, or even an empty bottle.
