It seems that invisibility has been invented!

If there is one technology that is useful and not actually a weapon, it has to be invisibility! With this technology you can sneak into places, spy on people and even cause havoc if you like, but if you thought that this technology was still on the drawing board then think again. This sign clearly shows that somebody is using invisibility, although it appears to be having some teething problems!
