    To make eight tentacles, cut strips of large bubble wrap on the diagonal between bubbles, varying lengths by taping two or three strips, end to end, with clear tape.

    Cut 16 strips of small bubble wrap 22 inches long and 5 inches wide. Then shred and twist one long edge of each. Cut eight same-size strips of cellophane sandwiching each between two bubble strips. Cut two base strips from small bubble wrap, 10 inches wide and shred the long edges. Cut eight strips of small bubble wrap and shred one edge of each. Then hot-glue smooth edges of four strips to each center strip.

    Open the umbrella and cover any metal or black parts with white tape. Tape thin tentacles to the inside rim of each umbrella panel and tape the thick tentacles to the cross spokes at the top of the umbrella. Be sure to glue the smooth edges of the tentacles to the umbrella spokes as plastic will melt.
