No reviews

A simple recycled craft made with cardboard, drinking straws, string, and paint, allowing children to explore the connection between pulling one cord and moving a finger.

  • Total Time: 150 minutes

Ingredients

  • 1 piece of corrugated cardboard measuring 12 inches by 9 inches, about 1/8 inch thick
  • 5 drinking straws, each 7.75 inches long, any color
  • 5 pieces of smooth cotton yarn, each 24 inches long
  • 1 sheet of plain paper measuring 8.5 inches by 11 inches for a hand template
  • 1 bottle of washable craft paint, 2 fluid ounces, optional
  • 1 small paintbrush, about 1/2 inch wide
  • 1 pair of child-safe scissors, for supervised use
  • 1 pair of adult scissors for cutting straws and thicker cardboard
  • 1 pencil
  • 1 ruler measuring at least 12 inches
  • 1 glue bottle of craft glue, 4 fluid ounces
  • 1 roll of painter’s tape, 1 inch wide
  • 1 drop cloth or recycled paper grocery bag measuring at least 18 inches by 12 inches
  • 1 small paper cup containing 2 fluid ounces of water for rinsing the brush
  • 1 clean cloth or 2 paper towels for spills and drying the brush

Instructions

  1. Cover the table with the drop cloth or a flattened paper grocery bag before you bring out the glue and paint.
  2. Place your hand flat on the 8.5-inch by 11-inch paper with your fingers comfortably apart. Trace around it with a pencil, then draw a simple wrist opening that is 2 inches wide and 2.5 inches long beneath the palm.
  3. Cut out the paper shape and place it on the 12-inch by 9-inch cardboard. Trace around the template, then cut the cardboard hand with adult scissors.
  4. Mark three short horizontal lines across each finger, spacing them about 3/4 inch apart. Lightly score the cardboard along each line with the closed edge of the scissors.
  5. Fold each finger gently forward and back at the scored lines. Do not force a deep crease.
  6. Cut the five straws into 15 pieces, each 1.25 inches long.
  7. Lay the cardboard hand face down. Place three straw pieces along the center of each finger, with one piece between each pair of fold lines. Leave about 1/4 inch of space at the fingertip.
  8. Secure each straw piece with a 1-inch strip of painter’s tape across its middle.
  9. Thread one 24-inch piece of cotton yarn through each finger’s three straw guides. Tie a small knot near each fingertip.
  10. Test one finger by holding the palm flat and pulling the yarn gently from the wrist end.
  11. Paint the front of the cardboard hand with a thin coat of washable craft paint, leaving the yarn and straw guides on the back untouched.
  12. Allow the painted hand and glued straw guides to dry for 1 hour.

Notes

Children ages 6 and up can help with this project under close adult supervision. Keep glue out of mouths and wash hands after painting.
