Supplies needed: 3 clear and 1 white bead, 1 blue pipe cleaner, 1 medium sized safety pin. Instructions: cut pipe cleaner double the size of the 4 beads. Loop the pipe cleaner through the safety pin and fold it in half. String the clear beads on first, and finally the white bead. P.S. We used these for World Thinking Day as a clean water project for Bolivia.
