    Wow that was amazing! 😀
    I know what I’m doing for the science tomorrow but….Mr Cain would baking be considered as science because I’m kind of baking some thing and I might save some for the class maybe

      Yes, baking can be considered as science – especially if you save some for me! 🙂

        well then here is the puff candy recipe ENJOY!! 😀

        Get a large, heavy-bottomed pan (like a soup pot) and put in the syrup, sugar, butter and water and set over a medium heat. Stir until the sugar has dissolved. Then turn up the heat and bring the mixture to the boil 2tbs of syrup 4tbs of sugar and 6tbs of water and a knife full of butter to stop it sticking.

        Leave it to cook (without stirring) until a teaspoon of the mixture turns into a hard ball when dropped into a cup of cold water.

        Add the vinegar and the bicarbonate of soda to the mixture. Be very careful when doing this as the mixture will rise VERY fast and after you put in the bicarb of soda it will start to look like golden foam!

        Pour it immediately into the lined tin and leave it to the side to set. Once the mixture has begun to set you can score it into squares to make it easier to break up later on. Leave to completely set. This is brilliant dipped in melted chocolate.

        That is how you make puff candy!!!

    The science afternoon was really fun! Even though my experiment wasn’t completely ready it was still fun watching the bubbles form! 😛 Mr Cain, when the egg is ready do you think I’ll be able to bring the egg in? Just so everyone can see what the final results are for it!
