Testing the Grabber

 In order to test our grabber, we gathered together a collection of common workshop items that can be found in any toolshed. We measured each item's weight in ounces using an electric scale. Next, we stated if the item was magnetic (and thereby influenced by the magnets attached to our grabber). We then proceeded to test if the grabber can successfully grasp the object and if the item could be held. We also used sticky tape to pin down the magnets but we soon noticed that the sticky tape could pick up light objects that were neither too big or too small for the grabber to grasp.
