Early Wake Up

After your victim is asleep reset the clocks so he or she will wake up a few hours early. You can try to trick one person or the entire family. Be warned that the victims may be especially grumpy from disrupted sleep, so use this prank with caution.

Suds-Less Soap

Certain things in life are expected. For instance, when you step in the shower, you expect your soap to create a lather. However, when you cover a bar of soap with clear nail polish, your victim can scrub with this coated bar for hours without seeing a single bubble. This is one of the best pranks to do at home for the sheer levels of confusion it can produce. Make sure there is a spare bar of soap, so no one is late for work or school.

Bed Switch

While two people are sleeping, pick them up and place them in each other's beds so they wake up completely confused. This prank will only work on sound sleepers, and it's most practical with small children who can be easily lifted. With the extra sneakiness and planning required, you can feel like you've pulled off a really big prank without the damage usually associated with larger efforts.

Flipping Out

Turn on the laptop or desktop computer running Windows, right-click on the desktop and select "screen resolution." This opens up a settings window. Change the "orientation" option to "landscape (flipped)" and the screen will flip upside-down, including mouse movements. Most people don't know how to change this and they'll be very confused with the upside-down computer screen.
