## Other Documentation

After the failled experiments from last week to get blue and pink, I tried again but a bit different. For blue i thought it failed because I had the wrong measurements, because i got it from this site: [https://yumuniverse.com/natural-dye-fabric/](https://yumuniverse.com/natural-dye-fabric/). But even with the same measurements it turned out green. I used 200gram red cabbage and 650g water and 1 teaspoon of baking soda. But it made no difference.

I also tried to make pink again and this time I decided to leave the vinegar out of it. So I used 2 to 3 tablespoons of beetroot and 240ml water. This turned out a bit salmon, orange/pink.&#x20;

At last I wanted to work with blueberries. So I used 38,2g blue berries and 300ml water for a very short time. This made the bioplastic yellow/ white.&#x20;

Unfortunately, attempt 10 to make blue failed again. I added sugar to the red cabbage water and the water turned transparent/ pink. I used 84,4g red cabbage and 400ml water. I let that simmer for 20 minutes and than added 4 tablespoons of sugar. It became completely transparant and so I added a little bit of extra blue water in the end (about 60ml). This made it turn a little bit pink.&#x20;

I cooked some avocado pits and looked at what that would do. First I put 6 avocado pits in water and let it simmer for about 45 minutes. This made a beautiful orange.&#x20;

Later I cooked the same 8 avocado pits with 2 teaspoons crystalsoda and 600ml water. I let this simmer for about 20 minutes. The water turned black redisch.

After that I cooked some union. This gave a yellow/ orange color.
