Cold sculpture

When it gets cold enough, water can be used as glue.

This can be illustrated with dry ice, which quickly wicks the heat out of metal (i.e. pennies) that comes into contact with it. Add a dab of water, put your surfaces in contact, and they stick.

If you're short of dry ice, Chicago specializes in producing the requisite temperatures for a few months at a time. Instead of having to conduct away unwanted heat, you can just radiate and convect it into the air. Things of pretty decent mass can be stuck together with a bit of water and patience:

Nothing up my sleeve.

Hollow leightweight things allow for even greater topological exploration.
