Volume reduction

Volume Reduction

All natural merpeople
To shrink things

Volume Reduction is the ability that all natural merpeople are shown to have. With this power, merpeople can shrink objects.

The first time we see the merpeople using this power is in "Sirena's Secret". Zac uses this power to improve Carly and Cam's vocal chords, while the mermaids used it to shrink lemons and Sirena's vocal chords.

This power isn't seen being used after "Sirena's Secret." This ability may be a branch of Telekinesis since that ability may also be used to apply pressure around objects by moving the surface of the object inwards and squeezing them.
