1. For an 8- to 9-foot rain chain, you will need about 40 feet of 1/4-inch soft copper tubing for large rings and 15 feet for small rings. (The tubing can be found in the plumbing department.) To create the rings, wrap the tubing around a soup can (for large rings) and a spice container (for small rings). Cut the tubing with pruning shears, working the pieces back and forth until they separate. Save 1 foot of the tubing to be used later.
2. Link the large rings into pairs, and join each pair with a small ring as shown.
3. Remove your downspout. Shape the 1-foot piece of tubing, and then place it in the gap as shown below. Secure the rain chain to the tubing.
4. Place a container underneath the chain to catch rainwater, and use the collected water to irrigate your garden.
