Customer Review: Great tent for the price
I purhased this tent after looking everywhere, online, dept and discount stores. I wanted a good sturdy tent that I could stand up in for car camping (tired crawling into my backpacking tents) I wanted something of decent durablity and quality, but didnt want to pay $400+ for a name like North Face, Sierra Designs etc... I did know that where I was going to use it could be VERY windy, so I decided against the dept stores. So far this tent has performed flawlessly, on a trip to Joshua Tree NP we encountered some some very gusty winds with no problems. You do need to make sure you really guy it out well using all the guy out points on the fly (have to buy rope and stakes for this) Once you have done this the tent is falrly bomber for a tent of its size and price.
Customer Review: gREAT dEAL!
This is a grat little tent. It has plenty of space for two adults and it withstood a Burning Man dust strom, more than once. It is easy to set up. i am a basic non camper so it only took me a few minutes to set this tent up and secure it. We loved this tent. Can't wait to try it again.

I'm fond of this project, because it can be done in any setting. Barometers are designed to be used indoors, so you do not need access to the outdoors.

This simple tool is a wonderful way to observe and learn about changes in air pressure. Use your webcam or camcorder to keep track of weather changes.

Barometer - Measure Air Pressure

Materials:

• clear, straight-neck glass bottle (about 12 oz.)
• clear glass jar (about 18 oz.)
• food coloring
• rubber band
• straight pin
• pot with water for testing the idea
• notebook, pen or pencil
• (optional) webcam, camcorder

Procedure:

1. Clean all labels from the jar and bottle

2. Fill the jar with water to just over the mouth by an inch.

3. Add a few drops of food coloring.

4. Tip the bottle and jar enough to let air bubbles escape.

5. Slide the rubber band onto the jar. Position it at the same level as the water.

6. Place the barometer in a place out of direct sunlight but where it is visible.

7. As the water rises and falls in the neck of the bottle, use the rubber band to mark the new level.

Testing this idea:

Take a large cooking pot and fill it with water. What happens to the water level when you press down on it? What happens when you remove your hands? Can you relate to how the non visible air around you would follow the same pattern.

High pressure happens when air is pressing down on the earth. What does your barometer do when there is high pressure? Low pressure happens when the air is rising. What happens to your barometer? What do the clouds look like when there's high pressure and when there's low pressure? Do you notice patterns during morning, afternoon or evening observations?

Weather is always changing. Use the barometer with other weather machines, like the anemometer, wind compass and hygrometer for a full picture of weather activity.
