Since a few of you asked, I thought I'd share how I made the "floating" specters I used in my Ghostbusters display this year. It's pretty simple to recreate and because of its size, has a great impact. You'll need: pvc pipe + connectors + glue, chicken wire, black cloth, cheese cloth, black gloves, thin gauge wire to attaching the cloth to the chicken wire frame, thicker gauge wire to use to form the hands. If you don't have dirt to stake the pipe into, you'll also need a bucket and cement…
