Hokey Pokey Experiment - Mmmmm...

The science behind Hokey Pokey:
When the golden syrup and sugar are heated it causes a reaction with the baking soda which creates carbon dioxide. The carbon dioxide is trapped in the heavier syrupy mixture which causes it to fluff up into the thick golden mixture. As it cools it sets into a firm solid. 

When broken apart it should have large craters (holes) to show where the carbon dioxide was.

5 Tbsp Chelsea White Sugar
2 Tbsp Chelsea Golden Syrup
1 tsp baking soda

Stir occasionally, if necessary, to prevent burning. Remove from heat. Add bakingsoda. Stir quickly until mixture froths up rapidly! Pour into a buttered tin immediately. Leave until cold and hard then break into pieces.

 Everyone thought hokey pokey was cool to make because they were going to get to sample it...

 But when we added the baking soda and the chemical reaction happened, there was a chorus of 'WOAH''s from every direction. It was cool to see how one little ingredient can make the sugar and golden syrup go crazy all over the place!
