Blistering (Gimmick and Online Instructions) by Alex La Torre

Cause a piece of gum to magically jump to four different portions of the hermetically sealed packet. If you are looking for visual magic to perform live or for a camera, this is ten seconds of sheer magic. It's not just a clever trick for video though; it's a practical and workable attention grabbing trick. What's more, at the end, you can immediately hand out the package for examination.

There's no assembly required. You receive a precision-made gimmick and will be ready to perform at a moment's notice.
