Pink Bottle 01

Today we did an experiment for Science Week. For this experiment you need vinegar, washing up liquid, food colouring, bread soda and an empty bottle. Pour vinegar into the bottle until 3/4 full. Put a large squirt of washing up liquid into the bottle. Then we put food colouring into the bottle. Mix the ingredients together by twirling the bottle. Make a funnel with paper and pour a heaped teaspoon of bread soda into the bottle. An explosion happens! The vinegar is an acid, the bread soda is a base. When they mix they create carbon dioxide which causes a fizz or bubbles. It was great fun to watch and it was our last experiment for Science Week.
