The Invisible Wire

you're probably shocked and interesed. It isn't a really invention, but it's a great idea

First: you need a computer. Why? Beacuse there's a "rope" that permites to trasform a long pc's cartridge into a short one.
Second: pull off a little piece of the "rope".

Use the wire like an invisible wire! You need to show the wire with a dark background so the people can't see it (the best colours are: black, brown and similar colours).

Hope you like it and remember: every month there's a new idea (more better than the last)!
