Let's make a concrete hand.
Almost as good as a real one. Certainly heavier.
Rubber moulds can make useful formwork. Gloves are an interesting shape so I thought I'd give it a go.
I needed to add a bit more water to the mix, as it had already started curing by the time I came to fill the glove. Other than that, no change to the mix was made. I used the same wooden spoon to spoon the mix into the glove, and tried to shake it as much as possible to work the trapped air bubbles to the surface.
Note I did this outside, as there was likely to be some spillage.
The glove bulged slightly due to the weight of the concrete. If I were to do it again I would try to squeeze the palm a little more to retain a more human thickness of the hand overall.
Once the glove was filled, I hung it from the back of an old garden chair to keep it in the right orientation whilst the concrete fully cured.
