I am making a theft proof box that could be markatable. In order to prevent the hardiest of thieves from breaking into it, I want to make it so difficult, that if the thief tried to cut/drill his way into the box, the material will grab onto the drill or blade of a saw and sieze it. The only thing I can think of is sandwiching some heavy gage stainless steel scrubbing pads between two layers of material. The stainless steel pad would wrap its self around the blade,drill making it extreemly difficult to cut open the box.
Now, I have heard of liquid armour. Seems a professor from univeristy of maryland created this liquid that would become very viscous when the fluid is mixed. Its strong enough to stop a shank from penatrating a bullet proof vest, which amrid fiber or kevlar, has a difficult time of stoping a shank from penatrating the vest.
Can anyone think of materials such as plastics that can make a thiefs life misserable to penatrate a box?
