Can You Create a Dew Collector with Household Items?

April 5, 2026

Quick Answer

A dew collector made from household items can be a simple and effective way to collect water in dry environments. This DIY device uses a plastic container, a plastic bag, and a few other common items to capture dew and condensation.

Gathering Materials

To create a dew collector, gather the following materials:

  • A clear plastic container (1-gallon or 2-liter)
  • A clear plastic bag (at least 1-gallon size)
  • A piece of string or twine
  • A rock or weight
  • Scissors
  • A pencil or marker

Assembling the Dew Collector

Cut the bottom off the plastic container and flip it upside down. Cut a small hole in the center of the bottom of the container and tie the string or twine around it. Place the plastic bag over the top of the container, securing it with the string or twine. Place the weight or rock on top of the bag to keep it in place.

Using the Dew Collector

Place the dew collector in a location that will experience condensation or dew, such as under a tree or in a shaded area. The plastic bag will collect the dew and condensation, which can then be poured into the container. The container will be able to hold up to 1-2 cups of water, depending on the size and the amount of condensation or dew collected.
