We never sit here under the weight of all this air, the 5 x 10^18 kg of atmosphere that sits above everyone on Earth, and say “Gosh, that sure is heavy!”

You don’t realize just how powerful that 1 bar (~100 kPa) of pressure is until a train car is filled with steam, allowed to cool, and then implodes ohmygod did that just happen?

Gas law at work. Near effect

Have you noticed the Mosquitos are already out! Here is a homemade trap to help keep you and the kiddos from being a blood donor!!!

HOMEMADE MOSQUITO TRAP:
Items needed:
1 cup of water
1/4 cup of brown sugar
1 gram of yeast
1 2-liter bottle

HOW:
1. Cut the plastic bottle in half.
2. Mix brown sugar with hot water. Let cool. When cold, pour in the bottom half of the bottle.
3. Add the yeast. No need to mix. It creates carbon dioxide, which attracts mosquitoes.
4. Place the funnel part, upside down, into the other half of the bottle, taping them together if desired.
5. Wrap the bottle with something black, leaving the top uncovered, and place it outside in an area away from your normal gathering area. (Mosquitoes are also drawn to the color black.)

New Plasma Device Considered The ‘Holy Grail’ Of Energy Generation And Storage

Scientists at the University of Missouri have devised a new way to create and control plasma that could transform American energy generation and storage.

Randy Curry, professor of electrical and computer engineering at the University of Missouri’s College of Engineering, and his team developed a device that launches a ring of plasma at distances of up to two feet. Although the plasma reaches a temperature hotter than the surface of the sun, it doesn’t emit radiation and is completely safe in proximity to humans.

While most of us are familiar with three states of matter – liquid, gas and solid – there is also a fourth state known as plasma, which includes things such as fire and lightning. Life on Earth depends on the energy emitted by plasma produced during fusion reactions within the sun.

The secret to Curry’s success was developing a way to make plasma form its own self-magnetic field, which holds it together as it travels through the air.

“Launching plasma in open air is the ‘Holy Grail’ in the field of physics,” said Curry.
