Part of a university project, I have created a sleeve which two people wear. An arm either end, goes in and attaches in the middle with carabiner clips to a bracelet worn. This object is used to stop police from separating 2 people, like a road block but with human bodies, the outside of the object is designed to be dangerous, making it harder for police to detach the protesters. You can stand sit or lie down with this object. I have designed it so that it is more comfortable when you put your arm into the cylinder. I have wrapped wire and attached bolts to the outside to show the caution you must take to get rid of this object!
