					This is a simple and fun activity to help visualize the warping of space by gravity. Stretch and fasten flexible fabric over the top of a bucket and encourage visitors to experiment with marbles and weights to discover some basics about gravity and black holes.<br /><br />Possible topics:&nbsp;Discuss an what an Earth-mass black hole would behave like vs the regular planet Earth and discuss what exactly &quot;center of mass&quot; means. You can also orbit marbles around a black hole!<br /><br /><em>Uploaded: October 2008</em>
