Scientists at Harvard University have been able to grow microscopic crystals into dainty "flower" structures on a beaker of chemical fluid.
The growth of crystals can be controlled to create intricate molecular objects. Two chemical compounds are dissolved in water in a simple glass beaker.
As CO2 enters the beaker from the air, it triggers reactions that result in forming microscopic objects, a process which takes up to 4 hours.
By manipulating th mixture's conditions, like adding some acid or kitchen salt, a large diversity of shapes-from vases to corals-can be made.
What will they think of next?
