Coca Cola Experiment

 We have been doing more experiments about food and what ingredients are in our food. We looked at the ingredients in a coke bottle. They were water, sugar, colouring, and acid.

 To find out how much sugar was in a coke bottle we decided to evaporate the water by boiling it in a frypan on the stove.

 When the water has evaporated we were left with a sticky black mixture. We poured this onto some baking paper. This is what we were left with. This is just sugar and food colouring.

 If we crushed this up we think this would be about 5 teaspoons of sugar.

So imagine drinking a bottle of fresh water and then being offered 5 teaspoons of sugar to eat.

 We also boiled the water off some orange juice.

There is a lot of sugar in orange juice too - a lot of this is pulp though.
