Cat and Mouse:
Cut a tiny piece of paper to fit undetected under your target's computer mouse. Write `Gotcha!` on it then stick it on the device with some tape. When they try to use it, it won't work. A peek at the bottom of their mouse will let them know they've been pranked!
Cookie Monster:
Unscrew several creme sandwich cookies and replace the filling with toothpaste. Sandwich the cookies back together and serve with milk, or water to make it look like a totally normal snack. How disgusted they are probably depends on the flavor of the toothpaste you use for the prank!
Delivery Day:
If you tend to get a lot of deliveries each week (Amazon, Flipkart, etc.), then this is a good April Fools' prank for your family. Save the boxes for a few weeks, then on April 1 set them all out by the front door to trick them nto thinking you went on a shopping spree!
Rainbow Shower:
Unscrew your showerhead and pop in organic colour so your family member takes a shower that makes him colourful!
Choco Poop:
Pretend that you're going to the bathroom and call your kid asking for toilet paper. When they come into the bathroom handing you the toilet paper, `accidentally` smear melted chocolate (which looks like poop) on their hands as they pass off the roll!
Salt and Pepper:
Open up a salt shaker and tuck a piece of paper towel over the top, then fill it with salt/pepper and screw the lid back on. The person using it is in for a surprise!
Full the cistern of your toilet seat with a shampoo or liquid soap. The victim of your prank when flushes it, will experience foam all over!
Duct tape your friends legs while he is asleep. But be careful that there isn't any sharp-edged object near him, which can cause some injury!
Announce about the engagement of your friend on Facebook and tag him!
