Time Experiments: How to make an explosive clock. How to use a watch as a compass.

See this note from SKRIBE:

"Your solution to 'How To Use A Watch As A Compass' only works in the Northern Hemisphere. In the Southern Hemisphere you need to point the twelve (the one if on daylight saving/summer time) at the sun, then NORTH is half-way between the hour hand and the twelve. Neither solution works on or near the equator. The further away from the equator the more accurate the results."
