Shaylin's Invention

Shaylin's class has been learning about simple machines and had a homework assignment to invent something using a simple machine. Shaylin came up with the idea to invent the "Friend Finder." Using a pulley system she made a 'screen' that the prospective friend puts their face in, and then a 'computer screen' to the right that tells her all about them and whether they would make a good friend of not. Here's a picture of her trying it out with her sister.

Looks like the "Friend Finder" thinks they could be good friends.
