Hi! In this instructable, I am going to teach you how to scrape your arm! There are two good ways to do this:

1. Get a running start on some concrete, trip, and go skidding across the ground, or 2. Do it the much less painful way that most people are more inclined to do, and fake it. Assuming you are going to go with the second option, here are the things you'll need:

Supplies

Glue (You can use most types of glue, for instance, a glue stick, liquid glue, clear glue, etc., but definitely avoid super glue or wood glue)

Step 1: Determine Where You Want to Scrape Yourself

First, figure out where you want to scrape yourself. In the picture I chose my arm, but this could be your hand, forearm, knee, leg, or really anywhere that would make sense. You may want to take off any bracelets you have on. Then, wash and dry that area.

Step 2: Apply the Glue

Apply a little line of glue to the area (A little goes a long way).

Step 3: Spread the Glue Around and Let It Dry

Next, spread the glue so it looks like the picture. Then, wait about five minutes for the glue to become clear (see picture.) The second pic is what it should look like when dry.

Step 4: Set Up for the Prank

Now you are ready to fake a scrape. First, get a running start on the concrete... No, just kidding! Secretly, when no one is looking, start rubbing or scratching the glue until it looks like a realistic scrape. Then, in a populated area, fake a trip and start groaning in pain as you show people your scrape. You can take it from there as for whether you want to tell them it's glue or not.

Step 5: Clean Up

To clean the glue off, just wash it off in water and your arm will be as good as new! If you liked this instructable, please vote for me! As always have fun!
