How did a nineteenth-century dressmaker revolutionize science? Jeanne Power was creative: she wanted to learn about the creatures that swim beneath the ocean waves, so she built glass tanks and changed the way we study underwater life forever. Jeanne Power was groundbreaking: she solved mysteries of sea animals and published her findings at a time when few of women’s contributions to science were acknowledged. Jeanne Power was persistent: when records of her research were lost, she set to work repeating her studies. And when men tried to take credit for her achievements, she stood firm and insisted on the recognition due to her.

Why Does Bleach Make The Color Fade
Depending on the concentration of bleach and how much you use your ink may fade or completely disappear.
What makes inky water clear up is the sodium hypochlorite in the bleach and that oxidizes the food coloring.
The color molecules remain in the water, but their shape is changed which means that it no longer absorbs and reflects light the same way and loses its color.
Amazing Disappearing Octopus Ink
You will need:
- Large clear bowl
- Plastic octopus
- Water
- Food coloring
- Bleach
- Dropper
First, place your octopus on the bottom of your glass jar or bowl.
Fill the container with water until your octopus is completely covered.
Add a few drops of food coloring and talk about what happens as the water darkens around the octopus. Why do they do that? How does it help them?
The ‘ink’ creates a great veil for them to get lost in, we could barely see him in the water.
Now begin adding bleach a few drops at a time until the water, we started with the blue and while it is a fantastic demonstration for how they use it to hide and escape it would not disappear no matter how much bleach we added.
So to demonstrate our disappearing ink experiment a little better we tried it with yellow which has a much more dramatic reaction to the bleach.
Add the bleach a dropper full at a time and watch the magic happen.
As you add more bleach the yellow begins to disappear almost completely from the water.
Extend the lesson-
Try all the colors to compare the differences, use cold water and also try it with hot water. Was there any difference?
