Substanciakinesis is the power to turn water and all things that contain water into a substance similar to crystal or glass.
With this power, merpeople can harden the water in their favor and rendering it indestructible (unlike ice, that would eventually melt away or break). It was also shown that if Bella wants, the water will return to its normal state after a few seconds, but if she will not, the water will forever be rigid.
There are many things about this power that are still unknown. It can be guessed that Mako Island and the Sea Caves of Ireland have different water-affiliated powers and abilities to be given.
Another theory is that the moon pool give water-based powers of the 4 nature elements, and because Cleo has Aerokinesis (air), Emma has Cryokinesis (water), and Rikki has Pyrokinesis (fire), so when Bella's powers upgrade she might get Geokinesis (earth) - the power to control the earth. However, because the series has ended, it is unknown if she ever enhanced her power.
- This power, along with Gelidkinesis, are the only ones from H2O: Just Add Water, that are yet to be shown in Mako: Island of Secrets.
- It is possible that only mermaids from Ireland have these powers.
