Safe­ty pre­cau­tions

Warn­ing! Only un­der adult su­per­vi­sion.


  • dish­es;
  • new needle­less sy­ringe;
  • 4 g (1.5 tsp) ed­i­ble sodi­um al­gi­nate and 20 g (6–7 tsp) cal­ci­um lac­tate;
  • 300 mL (10.2 fl oz) wa­ter;
  • 100 mL (3.4 fl oz) soda;
  • blender.

Step-by-step in­struc­tions

Blend 4 g (1.5 tsp) sodi­um al­gi­nate with 100 mL (3.4 fl oz) wa­ter. Add 100 mL (3.4 fl oz) soda and blend again. Dis­solve 20 g (6–7 tsp) cal­ci­um lac­tate in 200 mL (6.8 fl oz) of wa­ter and trans­fer to a bowl. Fill a needle­less sy­ringe with the so­lu­tion of sodi­um al­gi­nate and soda, and squeeze it into the cal­ci­um lac­tate so­lu­tion in the bowl – this cre­ates an ed­i­ble jel­lo-like worm with soda in­side.

Process de­scrip­tion

When the sodi­um al­gi­nate and cal­ci­um lac­tate so­lu­tions mix, they in­stant­ly form a new in­sol­u­ble jel­lo-like com­pound, cal­ci­um al­gi­nate, yield­ing elas­tic tubes re­sem­bling worms.
