I made this human hand with cement..( A Decoration piece made by me )
Very simple and easy method..
The things you need is just...
Cement + Water + Plastic gloves/Rubber gloves
All you have to do is just....
Add 1 glass of water in half packet of cement and mix it well remember or make sure that the mixture of water and cement should be thick after that just put this thick mixture of water and cement into plastic gloves and then you can place that gloves into any bowl to give it a better hand shape ..
You can also use plaster of Paris in place of cement:)
I made this hand after watching this tutorial on YouTube you can also try it

In this tutorial he made a pair of hands with cement so he used pair of gloves but I made only 1single hand so thats why I used only 1 glove ..
