Bunny Money

Joel's modification

One of my favorite performance pieces/party trick models is Robert Neale's Bunny Bill.  I learned it from Joel Bauer, who tweaked the spring mechanism to give it a bit more springiness.

Jeremy Shafer was challenged by his friend to come up with a 21st century reimagining of this 20th century classic:

The rabbit is of course more handsome here; and Shafer's pop-up mechanism is very cool; but I certainly won't ditch Neale's model, as it's quick and simple; and only requires one hand to give a delighted gasp of surprise from an unsuspecting audience.
