I've seen the classic Haunted Pack trick, and have an idea of how it's done, but am not sure the best props to use. Can you recommend anything for less than $50? I've looked at the Tarantula and M5, but those are out of my price range.
Thanks! I was thinking about Loops, but I wasn't sure if that was the answer, or if there was a better option.
The other is "Static" by David Jade, which can be found in the Tricks section here on theory11.
