Bottle Cages

These cages fit nicely over pint-size deli containers, such as cottage cheese tubs. Containers can be recycled after home use or purchased in bulk at restaurant and supply stores.

Materials Needed:

· organza fabric or silk screening material (1-2 yds.

· hot glue gun and sticks (1 per team)

· clear, two-liter soda bottles (1-2 per team)

· hand-held hair dryer

· Exacto knife and/or scissors

Instructions:

Begin with any clean, clear, two-liter soda bottle, top loosened or removed.

1) Use a hand-held hair dryer, on low setting, to warm and soften the glue on the bottle label. Remove the label and discard.

2) Use a razor blade cutter, scissors or knife to cut a rectangular

opening (air vent) in the side of the bottle.

3) Cut off the bottom of the bottle just above the molded base.

4) Cut off the top of the bottle, 2" below the top of the cap.

5) Cut a rectangular piece of netting (organza, organdy, or silk

screening material) to fit the air vent plus 1/4" all around.

6) Place the netting over the outside of the opening and secure with a smooth bead of hot glue around the edge of the netting.

Make sure it is thoroughly sealed.

7) Cut a round piece of netting for the top of the cage. Size by

tracing the cage top.

8) Hot glue the netting to the top of the cage. Avoid bunching

or pleating the netting.

9) If necessary, cut four to six, 1/2" long slits along the bottom of the cage and crimp inward for better container fit.
