If you are hoping to play a practical joke on a friend, but can't think of a good idea, you may want to consider using your computer as a tool to help you. You can quickly set up a scary image to pop up on the computer to startle your friend when they least expect it. With a little knowledge of basic computer software, this type of practical joke is easy to set up and is a harmless way to prank your friends.
Choose a scary image. Open your web browser, and use Google Image Search, Picasa, Flickr or another image search engine to find a scary image.
Download the image to your computer. Right-click the scary image, select "Save As" and click "OK." Wait for the download to complete, and locate the image file on your hard drive.
Open the screen-saver menu. If you are using a Macintosh computer, click the Apple menu, select "System Preferences," choose "Desktop and Screen Saver" and click on the "Screen Saver" tab. If you are using a Windows PC, open the "Control Panel" from the "Start" menu and select "Appearances and Themes," then choose "Display."
Apply the screen saver. If you are using a Mac, locate the scary image file you downloaded using the file browser on the left side of the screen-saver menu. Click the image and use the timeline at the bottom of the menu to set the idle time necessary to activate the scary-image screen saver. If you are using a Windows PC, use the image browser at the bottom of screen-saver section in the Display menu to find the scary image. Use the drop-down menu to set the number of idle minutes before the screen saver starts.
Test the scary-image pop-up. Do not touch the computer mouse or the keyboard for the amount of time you set for the screen-saver display. Make sure that the scary image pops up as soon as the screen saver begins.
Tips & Warnings
- Set the screen saver to appear after 1 or 2 minutes of idle time to ensure that your victim is still looking at the screen when the screen saver is shown.
- Do not scare anyone with a heart condition, health condition or that may have problems resulting from being startled.
