Counting particles from space

Article Abstract:

Cosmic rays, particles from deep space that enter the earth's atmosphere and precipitate a chain-reaction of particles, are observable and measurable with the use of a telescope that can be built at home. Step-by-step instructions are given for building such a device and equipping it with a home-made Geiger-Muller counter.

Sensing subtle tsunamis

Article Abstract:

Scientist Paul Neher of Las Cruces, NM has devised a manometer that can detect atmospheric tsunamis. The device, which costs about $50, works by balancing the barometric pressure against the air pressure present inside an aluminum bottle, which is a bit warmer than the surrounding air.
