using gas pressure- you could viably just use an air pump till the sculpture could no longer hold it.
like a balloon popping, without the need for any special chemicals, just a pump. CO2 pumps could also work here, as could dry ice in warm water, or a bit of liquid nitrogen.
Alternatively, vinegar + baking soda= CO2 so mixing that inside it will lead to a pressure build up with a harmless gas- though foamy.
(I'd go for the first option, maybe with liquid N2, as its reliable and incredibly simple.
