Magic Ball and Vase

thingiverse

Here's a clever magic trick that will leave your audience wondering how you managed it. It's called the Magic Ball and Vase illusion, and with some simple preparation, you'll be able to perform it like a pro. First, obtain two identical halves of a ball, which are meant to be glued together later. To keep them perfectly aligned while they're still separate, use a small centering pin that fits snugly into the gap between the two halves.
