I had no money for this so project I got thing that I could find at my houes and at no cost to me. The materials I uesd were a water bottle,and rice. The first thing I did was to put some rice in the water bottel. After I put sime tape so the rice would not fall out. My weight weight about 1.4 pounds.the step that I did is that I added rice inside my water bottle and tapped it with tape so I can do decorate it. It took me about 20 minute. This is to work out and built my biceps and my upper body. I did it at the last minute. It could be used for hand therapy. Most of the time free weight cost a lot. A free weight can be made out of any thing. You can make a free weight for any thing. Don't have to waste money for when you need a new that weights more.
