Blue Bottle Experiment

Hi there!. This is a simple experiment. There is a bottle contain a liquid like water. When it shake, that liquid turns blue color. Just try to do it.

Chemicals that we are using in this experiment are easy to find.

1. Sodium hydroxide
2. Glucose

3. Methylene blue (This chemical can be found from stores that sell aquarium fish.)

4. A volumetric flask

if you don't have a flask, you can use a bottle. (glass or plastic)

first get 1 gram of sodium hydroxide.(if you don't have a scale, just get a very little amount.) now dissolve it with about 20ml of water. (cold water is better)

Not get 5 grams of glucose and mix with 40ml of water. Then add few drops from methylene blue and mix it again. Then add it to the flask. (or bottle)

This is the final step. now add sodium hydroxide solution to the flask and mix it. Now wait for a few seconds.

after few seconds the solution turns colorless. Now shake the bottle. It turns blue. and again after few seconds the solution turns colorless.
