Animated Halloween Cake

Step 3 Jumping Spider

I also really like the jumping spider on the pumpkin. Very easy really. A 3 rpm motor with and spring piece of metal rotates below. The spider has a wire (rod) going down through the cake that lines up with the springy metal. There is a bracket that blocks the springy metal as the motor rotates toward the rod. Once the motor goes so far the spring finally pops off of the bracket and pops the spider’s rod which shoots him up. So he jumps about every 20 seconds.

In my haste I didn't get a picture of the underside of this mechanism despite hours of testing to make sure the jump was perfect.
