Jelly 'fibre' approx 22 cm long

To make the jelly fibre you need

  • mould approx 2 cm x 2 cm x 24 cm (can be made from a length of electrical trunking with pieces of plastic credit card glued across the ends) 
  • cling film to line mould 
  • 15 g powdered gelatine (preferably not the ‘veggie’ sort as it does not set well) 
  • 150 ml water 

Mix the gelatine according to the instructions on the packet and pour into the lined mould. 

When set, use the cling film to lift the jelly ‘fibre’ from the mould.
