Concoction of the Beast

[from left to right]
Aluminium Foil as Mould
Cement:Glass:Water = 2:1:1
Wood as Mould; Cement:Sand:Water = 2:1:1
Plastic Wrap as Mould
Cement:Styrofoam:Water = 2:1:1


Too much water, the volume will decrease after a while, as water evaporates.
Aluminium foil reacted with the concrete mix.
Glass was a bit too small to have achieve the visualised effect of sparkling surface.
Styrofoam can help decrease the net weight.
Plastic Wrap has the best effect so far.

Then again, the tip is still yet to be achieved.
