April Fool is coming. Here's a fun prank that I am going to use on my friends, and I would like to share it with everyone here at Instructables. As someone opens the door, they will get slapped in the face. It wouldn't hurt much but sure will surprise them.

Please VOTE for me if you like the prank. Thank you.

Step 1: Gather Materials and Tools

Everything you need is showing in the picture.

Step 2: Make a Hand Cut-out

Put your hand on the cardboard and draw around it.

Cut out the cardboard hand shape.

Step 3: Cut Plastic Strips

Cut 4 pieces of plastic strips (about 2"x8") from the plastic clamshell packaging.

If you want more slapping power, add more plastic strips.

Step 4: Assembly

Stack the plastic strips together and staple one end.

Place the cardboard hand on the other end and staple them together.

Step 5: Tape It Up

When you ready to prank someone, tape it up to the inside door frame trim as showing on the picture.

Make sure you tape it to about the face height of the person you are pranking.

Make sure to use on door entry that swing in such as bathroom and bedroom entry.

To close the door after you tape it up, stand outside the door, push plastic in with one hand to clear the door way, and close the door with your other hand.

As someone opens the door, they will get slapped in the face. It wouldn't hurt much but sure will surprise them.

If you like my prank, please VOTE for me. Thank you.
