Whisk all jelly slime ingredients together in a medium pot.
Place pot on medium heat and bring slime mixture to the boil.
Once boiling, cook stirring for about 2 minutes until clear.
Let cool slightly, then add glitter and mix through.
Pour onto a baking tray with a lip, or into a baking dish and leave in the fridge to set for about 30 minutes until firm.
Break up mixture with a spoon (or use your hands), then get squishing!
