The wonders of Baking Soda!

We had a serious look at Sodium bicarbonate or Baking Soda today. We knew that when mixed with vinegar, it froths up but were not sure why.
We've found out that when it gets mixed with something a bit acidy there is a chemical reaction and the baking soda gives off Carbon Dioxide (CO2) in bubbles.
This cool reaction happened when we mixed the baking soda to a melted golden syrup mixture (which is slightly acidic). This carbon dioxide gas, which formed when the baking soda was mixed with the boiling golden syrup enlarged, creating little air pockets in the hokey pokey. Very yummy too!
