Another rotating wire effect (Fig. 4) can be obtained by shaping the wires as shown in Fig. 11B with the ends pointing up.

A real rotating pinwheel is a new experiment possible with the added power of this coil Make the wire and pivot according to Fig. 12. When you throw the switch, vivid lavender discharges at the ends of the wire vane exert thrust and start the wire to rotating. It soon builds up to a fairly high speed and forms a ring of lavender fire with bursting discharges (Fig. 5).

The lamp experiment (Fig. 6) which could be performed with the first coil is even better with more power. Attach a short piece of stiff wire to one terminal of a porcelain lamp receptacle with exposed screw terminals. Form a loop in the free end of the wire and fasten it to the top end of the coil with a 1/4-20 nut (Fig. 6). The other terminal of the receptacle is not used. Screw in a 200-watt clear lamp and throw the switch. Beautiful rose colored wavering flames seem to float from the filament to the glass. The main wires supporting the filament are lighted in lavender for a colorful contrast.
