Invention Fair

Abby's 4th grade class held an Invention Fair the other day. Each student had to come up with an invention based upon a problem they, or someone they know, have and create a pro-type.  It was so fun to go to the fair and see all the great ideas!  There are some creative kids in her class! Abby's invention was a guinea pig feeder that attached to the side of the cage with an untippable try :-)
