I had no money for this project. I got thing that I could find at my houes and at no cost. 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. My weight weight about 1.4 pounds. I tapped it with so I can do decorate it. It took me about 20 minute. This is to work out your hand. I did it at the last minute because I was being lazy. 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. You can just make it your self at little or no cost to you.
