1. Fit the stem of a funnel inside the short end of a straw. Push the funnel in as far as it will go. Securely tape the straw to the funnel. Repeat for the second straw and funnel.
2.Push a straw-funnel assembly through the hole near the bottom of each container so that the funnels are on the inside of the containers. Adjust the straw-funnel assemblies so that the funnels face up. Put some modeling clay around the hole, on the outside of the container, to hold the funnel in place.
3. Start by putting the long end of each straw through the hole in a plastic collection cup. Adjust the straw so that the funnel faces up. Put some modeling clay around each hole, on the outside of each collection cup, to keep each cup in place.
4.
The straw should slope down slightly from the box to the cup. This will allow gravity to help the water you collect flow from the straw to the cup. If there is no slope, the water will collect in the straw rather than in the cup. …show more content…
Keep cutting a little bit of the straw off and re-assembling until it is right.
Do not worry if the collection cups do not sit completely flat.
5. Cover the opening of one container with a single large piece of plastic cling wrap. To seal the container closed, pull the wrap tightly over the opening and tape it in place at the four corners of the container. Repeat for the second
