How to Make a Simple Rain Gauge
Things You'll Need:




2 liter plastic bottle (with consistent diameter)
Sharp scissors
Paper clips
Small bucket full of sand or gravel
1. Cut the top off of your plastic bottle. Cut about a quarter of
the way down, to where the bottle begins to have a consistent
diameter. Be careful to cut the edge as smoothly as possible,
salvaging both pieces of the bottle.
2. Remove the bottle cap and turn the top part of the bottle
upside down, placing it into the bottom part. Connect the two
halves with paper clips.
3. Place the plastic bottle rain gauge in a location where it will
easily collect rain without impediment from surrounding
trees, plants or buildings.
4. Help your rain gauge stand upright by placing it in sand or
gravel. Simply make a hole in the sand or gravel large
enough that half the bottle gauge sits into the pit. Use the
gravel or sand to support the edges of the bottle gauge.
5. Measure the amount of rain caught by your gauge by
emptying the contents of the bottle rain gauge into a
measuring cylinder.
