Make the light on your phone move around as though it has a mind of its own. No complicated gimmicks or accessories that you have to clip onto your phone. This is a self-contained app that can make the flashlight of any iPhone dance, zig-zag, and ping-pong around the back of the phone. Make your audience question reality when you perform Gaslight by Seth Race & Chris Hanowell.

Here’s what happens:

You turn on the flashlight on your phone to show everyone the bright light that is on the back of every phone. You put your phone down on a table and cover it with a handkerchief or napkin. With a magical gesture, the light on the phone starts to roam around underneath the cloth cover entirely on its own. You then remove the cloth and the flashlight is shown to be back where it normally resides, and the phone is completely examinable.

Gaslight is a specially built app that allows you to make it look like your flashlight has a mind of its own. The app is fully customizable, so it can work with any iPhone model currently supported by Apple. A little choreography is all it takes to make this illusion look perfect. Additionally, Gaslight can be combined with some of your favorite LED magic products to make it appear as if you remove the light from the phone and put it back on. This incredible app allows you to perform wild visuals using an object everyone carries in their pocket: a cell phone. This trick is easy to do and will find its way onto your home screen to be something you perform every day. Give your iPhone magic a ghostly kick when you perform Gaslight by Seth Race and Chris Hanowell.
