A Peltier module allows you to turn heat into electricity. Because you can place it in areas that are normally warm anyway, the electricity created is "free" in a sense, though it does work best when one side of the module is cold and the other is hot. In other words, all you'll need for this project is the Peltier module and a cooler surface such as soil or water, and a warm area such as a well lit window or warm pan.
In the first video, you'll see how contact between different materials can result in attraction or repulsion. Experimental results are discussed that led to Ben Franklin's one fluid theory of electricity. It explains how clues were found from rubbing different materials together.

This video tutorial is in the Disaster Preparation category which will show you how to use a map style compass. The first thing is to get your bearings by sight without a map. The arrow on the compass represents the direction of travel, the N on the compass dial is the compass North and the red needle points to the magnetic North. First align the compass N with the magnetic North. Now say you want to go 90 degrees East. Next you align 90 degrees with your direction of travel arrow. Rotate the...
Without good navigational skills, your expedition could lead to failure or result in a dangerous situation. Try to use a laminated map which is better in wet conditions. 1:25,000 scale maps provide the greatest detail. One grid square equals 1 kilometer. Use map keys for reference. Don't mistake boundary walls for footpaths. A compass points to magnetic north and the top of the planet is called true north. Magnetic north is constantly moving and its position relative to true north is differen...

Eddy Currents are little circles of electricity created when metals are moved by magnets or even when magnets are moved by metals. To understand this practically take a regular piece of cardboard and drop it in between a horse shoe magnet. It drops normally with out being effected by the magnet. This is because the cardboard does not conduct electricity. Therefore it does not cause any eddy currents. But instead if you use an aluminum piece in the same way, it falls very slowly, because alumi...

The parts of the compass are a base plate with different measurements for calculating mileage and distance. The magnifying glass is used to magnify things on your map. The arrow at the top of the compass is called the direction of travel arrow. To find the degrees on your compass, use the rotating bezel ring, with North being "0", East being "90", South being "180", and west being "270". The magnetic needle inside has a red magnetic north end, which is used to locate "North", and the black en...
