To answer this question we first need know how does cotton candy work; Cotton candy works by spinning sugar into candy floss strands using two cotton threads called bobbins. The two bobbins are suspended between two round frames called cones . The bobbins rotate around each other as they pass through two coarse sugar lumps known as “toppings”. Each bobbin produces one strand at a time as they spin around each other at high speed at approximately 3000 rpm . After each strand reaches its desired length it becomes sugar crystals instead of cotton candy . This can take from 5 minutes up until 10 minutes . Cotton candy lasts between 2-4 hours once produced , however its original texture starts deteriorating as it cools down . If you want to store your cotton candy for later use then keep them inside their original box so that they don’t get warm or cooled down when stored in another container . You can store them either in freezer bags or resealable plastic bags .
