10. Attach wires from the LED, battery pack snap, on/off switch, and
    potentiometer to the terminal blocks, as shown in Figure 9-14.


11. Use a mini hacksaw or a utility knife to shape foam blocks so that they
    fit inside the bottom of the pumpkin, as shown in Figure 9-15.
    We used the type of foam used to hold dried flower arrangements. You
    could also use packing foam.


12. On the side of the plastic pumpkin that will face the talking pumpkin,
    cut a hole just large enough to allow the LED socket to fit.


13. On the side of the plastic pumpkin that will face away from visitors,
    cut holes just large enough to allow the shaft of the on/off switch and
    potentiometer to pass through.

Be sure to wear safety glasses in case a piece of plastic flies off in the

wrong direction!
