The chocolate experiment was for a big company who make lots of chocolate with bubbles inside (im sure you can guess which one) They wanted some equipment building which would tell them how big the bubbles were insode the chocolate. They wanted to know this for lots of reasons. such as making sure every chocolate bar was the same, making sure the same amount of chocolate was in each bar (more bubbles would equal less chocolate) and detecting when any problems had occured during the manufacturing process
