We didn't appreciate this ball's incredible characteristics the first time we saw it. The Squiggle Ball has amazing abilities to navigate out of corners, even simple mazes! In fact, it's virtually impossible to block. Place this one on your classroom floor and watch it explore your entire room. The ball's transparent case allows you and your students to view the inner workings consisting of a specially weighted motor. Requires 1 AA battery (not included).Great Graphing Exercise!
Set the Squiggle Ball down on a tile floor and collect data on its position every ten seconds. Represent its path on graph paper.
