Problem: Article: Since rubber band balls are all about the challenge anyway, why not make it a little harder? Try expanding your ball without paying for any rubber bands. Here are a few places to look for them:  Ask friends and neighbors for spares. Ask postal workers, newspaper delivery people, and other door-to-door delivery workers. Look in shoe stores, which may use rubber bands to hold the shoe boxes closed. If you don't twist the rubber bands, they lie flat against each other, with no room for air. This makes the densest, bounciest ball. The trick to this is finding each new rubber band exactly the right size, so there's no slack when you loop it around the ball once. Rubber band balls are extremely dense, so after a certain point they'll be too heavy to bounce without breaking something. After that, the challenge is to make it as large as possible. You can even beat the world record, if you can find 700,000 rubber bands.  Once the ball is about the size of a basketball, wear safety goggles. Plenty of rubber bands will snap after this point, and you don't want them hitting your eyes.  Rubber bands decay over time. To stop it shrinking or breaking apart, your project will need regular reinforcement.
Summary: Find all your rubber bands for free. Make a ball without twisting any rubber bands. Make it massive.

In one sentence, describe what the following article is about: Place your aluminum piece on a sheet of aluminum foil with the shiny side facing away from the aluminum piece. Fold the foil over so it covers the aluminum piece but is not sealed. The aluminum foil creates distortions as well as a rainbow pattern on the aluminum due to the heat and chemical reaction. Keep the open ends of the aluminum foil facing upwards so that the water can run down into the package. Stack your pieces in the dish rack of the washer. Add powdered dishwashing detergent, like Cascade Complete or Finish Dishwasher Powder, to the dispenser. Then, add 1 teaspoon of trisodium phosphate (TSP) to the dispenser. TSP can be found at your local hardware or home improvement store. Age the aluminum by running the dishwasher on the pots and pans cycle. Turn on the drying cycle as well. After the cycle is complete, carefully remove the aluminum pieces from the dishwasher. Use caution, as they may be hot. Remove the foil around the aluminum. If you want to add more patina or increase the aged look of the aluminum, wrap the pieces in aluminum foil at a different orientation and run them through the dishwashing cycle again.
Summary:
Wrap your aluminum piece in aluminum foil. Load your aluminum pieces in the dishwasher. Fill the dispenser with powdered dishwashing detergent and TSP. Run the pots and pans cycle. Remove the pieces from the dishwasher. Repeat the process to add more patina.
