Common Investigative Equipment
Many ghost investigators use a variety of tools to aid them during the process of investigation. Most ghost investigating equipment can be purchased at a relatively low cost to the investigator or team. Conversely, some initial equipment may be more costly. Nevertheless, such tools can provide investigators and paranormal teams with the ability to increase the success of their investigation. So, what kind of equipment does a ghost investigate typically need? Find out here!

MICROWAVE OVENS: AN INTRODUCTION
Microwave ovens have infiltrated our lives to such an extent that life without them has become impossible. The ability of a microwave oven to quickly and safely cook food appeals to all of us. But how safe is it? This series of articles will study and analyze the microwave oven and its working in detail and try to give you an orientation as to what that little box on your kitchen counter really is. The first article is about the origins of the microwave oven and its components.

MICROWAVE OVENS: How safe are they? (I)
All of us have been using microwaves since as long as we can remember. There are fears that microwaves can cause damage to the human body. Let us see how safe microwaves are, and to what extent are we shielded from the much-feared microwaves. The text of the article is continued into next week’s article.
