She tries various things to get the jar, such as jumping or throwing her teddy bear at the jar in hopes of knocking it off the table, but to no avail. Eventually, almost by accident, she realizes that she can pull the tablecloth on which the jar sits and is thus able to reach the jar. In the future, she will be more likely to try this technique again since it was effective. This example best demonstrates
