This is what it looks like when finished.
Welding wood. This is a technique to join wood using scrap tin, such as that from a used can. Needed materials include:

1. Two sticks of wood to be joined.

  • Make sure the wood is in good condition where the connection is to be made. It should be clean, no bits of bark or loose paint, and no knots, as they are too hard for nails.

2. Two pieces of thin tin.

  • For the first bond, use a knife for cutting the tin from a small can for example.
  • Length and width equal to the stick diameter. (more steps follow)

Estuaries and coastal waters are among the most productive ecosystems on Earth.
Water is vital for all known forms of life. Covering 71% of the Earth's surface, it is found mostly in oceans and other large water bodies. 1.6% of the total mass of the Earth's water is below ground in aquifers and 0.001% is in the air as vapor, clouds, and precipitation (rain, snow and sleet).

The Earth's water moves constantly through a cycle of evaporation and transpiration (evapotranspiration), precipitation, and runoff, usually reaching the sea. Over land, evaporation and transpiration contribute to the precipitation over land - thus deforestation and other changes to land can have wide and long-lasting effects through their impact on the water cycle.

Some observers estimate that by 2025 more than half of the world population will be vulnerable to a lack of water. Appropriate water supply and water purification technologies can help.
