Alarm Clock

Get a small alarm clock and set it for 3:00 a.m. Sneak under the victim's bed. Once it goes off, he/she won't be able to find it will drive them nuts.

Apple in an Orange

Take the orange and cut just a little slit on the bottom or as much needed to get the inside out. Take the pulp of the orange out. Take your small apple and put it inside of the orange. Make sure, when showing friends, not to let them see the slit. When you peel the orange there's an apple inside. Don't make it obvious or they will know you planned it. They will be shocked.
Banana Splat

Take a banana and squeeze it until it's very soft to the touch then take the knife and cut three or two cuts on each side very lightly and set it down where some one can get it, when they grab it all the smashed up banana comes pouring out (but never try this on a teacher and think you wont get a detention trust me I KNOW).
Bloody Hand

First, get a shoebox. Mix some glue with red food coloring (you can also use colored hair shampoo). Cut a hole in the box near an end. When you have finished mixing the mixture of glue and red food coloring so it looks like blood, put your hand in the hole of the shoe box you made earlier and cover with the red goo.
