A Halloween costume made using two iPad 2s

For those shopping about for a Halloween costume, if you happen to own two iPad 2s, or are able to get your hands on a pair of iPad 2s, you will be able to hook yourself up with a pretty cool and unique costume which gives the illusion that you have a gaping hole in your mid section.

This effect was discovered by Mark Rober, a NASA engineer who figured out that by strapping two iPad 2s to your body, one in the front and the other in the back, and holding a Facetime conversation between them, you will be able to give off the illusion that you’re missing a chunk of your belly, as pictured above.

If you’ve missed out on or have already celebrated Halloween over the weekend, you can always keep this idea for use next year, or any time you simply want to prank a friend or family member. Check out the video here to see it in action.
