Here is a simple prank, borrow your friends Apple iPad or iPhone (I believe it works on Google Android smartphones too), download and change the wallpaper and pretend to drop his or her smartphone. Show him the shattered screen. Priceless. Works on the older iPhones and the the newer iPhone 6 and 7. If you are into pranks, you will also love this weeping angel prank for desktop Windows PC or Apple Mac
