text: Eletrospraying is used to create alginate spheres by pumping an alginate solution through a needle. A source of high voltage usually provided by a clamp attached to the needle is used to generate an electric potential with the alginate falling from the needle tip into a solution that contains a ground.  Calcium chloride is used as cross linking solution in which the generated capsules drop into where they harden after approximately 30 minutes. Beads are formed from the needle due to charge and surface tension.
  * Size dependency of the beads
  ** height alterations of device from needle to calcium chloride solution
  ** voltage alterations of clamp on the needle
  ** alginate concentration alterations
