WHAT DO YOU NEED:

· Goldfish crackers

· 6 paper towel rolls or wrapping paper roll cut into pieces

· 3 straws

· 3 empty ribbon spools

· baker’s twine

· small plastic cup or container

· masking tape

· scissors

· pen or screwdriver to poke holes in cup

1. Make the pulley basket: Take the plastic cup and poke two holes in it, directly across from each other. Feed twine through each hole and tie, giving the cup a short handle. Then tie a 1 1/2 yard piece of twine to the center of the cup handle.

2. Construct the pulley supports:

1. Cut paper rolls to desired lengths. I used 4 at paper towel roll length and 2 at a shorter length.

2. Poke a hole into one end of a paper roll, approximately 1″ from edge. Poke another hole, also 1″ from edge, directly opposite the circle from the first hole. Make holes large enough for a straw to fit easily through. Repeat with the remaining five rolls.

3. Take two matching height rolls. Feed a straw (the pulley shaft) through both holes in a roll, then the hole in a ribbon spool and then through the second roll. Repeat with the other two sets of rolls.

4. Tape the bottoms of the paper towel rolls to a stable table with masking tape. The rolls should be just narrower than a straw’s length apart. Then tape the next two pulleys.

3. Feed and play with the pulleys: Pull twine over the first ribbon spool, under the second ribbon spool and over the third ribbon spool. Fill the basket with Goldfish crackers and lift away! My daughter’s favorite part was making the basket go up and over the first pulley, making a shower of Goldfish crackers :)
