A new 3D Fruit Printer - a machine that prints three dimensional fruits has been developed by a UK-based company.

The printer makes use of a molecular gastronomy technique called spherification to convert liquid to gelatinous globules that resemble caviar or tapioca pearls.
For fruit juice, this means mixing the juice with alginic acid, which is then dripped into a cold bath of calcium chloride. The resultant reaction produces a skin around it which pops when it is bitten into.
