Plasma Ball USB

Friday, May 2nd, 2008


Powered by an included USB cable, this desktop Plasma Ball is about stands about 6 inches high and includes an on/off switch. While it emits a very low current, it does so at a relatively high-voltage and so it does produce some EMF. Respect your plasma ball and will respect you. All this made possible by the evil genius of Nikola Tesla and some science.

This is combination of interesting and fun gasses (like Argon) are first trapped inside a plastic sphere at relatively low pressures. An sporadic current, at relatively high voltages are pumped into the sphere via an electrode in the center. This energy causes atoms to be stripped from the gasses,leaving in its wake some positively charged ions and a gorgeous gaseous and electrically conductive environment (aka Plasma). That high voltage served up through the electrode will now arc up through the plasma to the lower voltage edge of the plastic sphere (starting at the top where the temperature is greater). The arcs glow because they are hotter than the surrounding plasma. You can touch the plastic and the arcs will strongly congregate to your touch because you will be creating an even lower voltage jump from the electrode.

Ultra Dental Water Jet by waterpik

Wednesday, March 19th, 2008


The Waterpik WP-100 Ultra Dental Water Jet is clinically proven to be more effective than floss for healthier gums. Most dental professionals recommend brushing and flossing to keep your teeth and gums their healthiest. Unfortunately, nearly 80-percent of Americans don’t floss on a regular basis, and most people find flossing to be a painful or unpleasant chore. Finally, there is an effective alternative to flossing that feels great and is simple to complete.

This tool has designed to deliver a water pressure of 10 to 90 PSI with 1200 pulses per minute. This system delivers a clinically proven mixture of water pressure and pulsation to remove debris and bacteria lodged deep between teeth and below the gum-line — three times deeper than brushing alone. Also, it massages and stimulates the gums to improve circulation and help promote strong and healthy gums.

Actually, there are over 50 published clinical studies that show the Waterpik Dental Water Jet provides significant oral health benefits, for people who wear braces, have diabetes, and have mild to moderate gum disease. That’s why Waterpik is the most recommended brand by Dental Professionals.
