A 6" hand held black light fixture with flashlight. Works with 4 AA batteries not included. Excellent for prospecting, checking hand stamps, finding pet stains, checking for bacteria, applying black light sensitive cosmetics, collecting insects, searching for antique glass, reading secret messages and our personal favorite... hunting for scorpions at night in the desert are just a few of the uses weÍve heard about. Very Popular!

| The weather forecast was made yesterday - now here comes Wiz Kid. Elegant design, innovative sensor technology, and the weather forecast presented by Wiz Kid the weatherman - these are just a few of the features of the new radio weather station. | ||
 |
The attractively designed weather station can be completely set up and ready to use in just minutes. It displays not only the weather data but also calculates the weather forecast for your immediate area and registers wind speeds as well as rainfall. It also provides you with other interesting information, such as the current phase of the moon, sunrise and sunset times, weather trends, room climate and more.
To find out quickly what the weather is going to be like, all you have to do is take a look at what kind of clothes Wiz Kid is wearing. Whether swim suit or scarf and umbrella, the Wiz Kid has over 50 variations for dressing appropriately for the weather just outside your door. As soon as it begins to rain and the sensor detects it, the Wiz Kid informs you by appearing with an opened umbrella - you donÍt even have to look outside to know. The large well-organised LCD, super flat and housed in the elegant silver-blue base station, shows you all of the important weather data in graphic and numeric formats when in normal mode. Other functions are easily accessed using only five buttons. |
 |
| Greatly contributing to the accuracy of the weather data is the new E9301 radio combi-sensor. It is fitted onto a mast that can be placed in the ground and works similarly to professional devices used in industrial applications. For example the outdoor temperature is measured in the same way as professional meteorologists: 6 feet above ground and shielded from sunlight.
In addition, the combi-sensor can be set up any place up to a distance of 300 ft. from the base station without having to lay cables or drill holes. Up to 8 additional locations can be used to place the E9305 sensors to measure the temperature and relative humidity and have the data sent wirelessly via radio to the weather station using low disturbance 433 MHz technology. | ||

Five nickel plated steel balls of uniform mass are suspended from the frame. The item comes fully assembled and includes instuctions with the theory explained.40-135 - Newtonian Demonstrator..............$19.95 |
Acrylic Refraction Cube |
Perfect for Index of Refraction and Total Internal Reflection experiments.
The bending of light as it passes from one substance to another is called refraction. Refraction causes the familiar mirage as we appear to see a nonexistent pool of water on a distant road on a very hot day. The ray of light can be totally reflected back inside the cube, leading to total internal reflection, not refraction. These and other phenomena can be studied with our Refraction Cube. The index of refraction is about 1.5, meaning that the light travels 50% faster in air than it does upon entering the acrylic plastic. Faces are 5 cm square, instructions included. 30-060 - Acrylic Refraction Cube..............$19.95 |

Secrets of the Tornado will show you how to make models of any size. Even
complex multiple vortex tornadoes can be created with just cardboard or
plywood, tubes, hair driers, a window fan or a vacuum cleaner, and a few other odds and ends.
The viewer's guide includes complete instructions and drawings. These interactive, fully-controllable models are the culmination of two years of work with the country's leading tornado modeling experts. Add special lightning effects with our Tesla coil.

You'll witness dozens of incredible tornadoes that can be seen nowhere else.
See the unbelievable raw footage from the "dillocam", a heavily weighted camera
placed, for the first time, directly in the path of a major tornado. And you'll
see how laboratory "storms" relate to actual tornado formation... even if you
never build a model. This video will change forever the way you think about tornadoes.
