SCOBY leather

* 350 g SCOBY
* 28 ml glycerin
* 50 ml kombucha liquid
* Blender x1
* 250 ml beaker x2
* Mold
* measure the glycerin- measure the kombucha liquid- measure the SCOBY
* Add the ingredients to the blender
* Blend until no strips remain 
* Pour in a 3-4mm thick layer.

Biorubber

* 122 ml water
* 60 gr corn starch
* 60 gr gelatin
* 122 ml glicerin
* 70 ml to hydrate the starch
* 250 ml beaker x2 
* 600 ml beaker x1
* Lab spoon x1
* Hot plate x1
* Digital scale x1
* Measure water - measure gelatin - measure glicerin- measure corn starch
* Mix the water, glycerin and gelatin in cold.
* Heat this mix to 80°C-85°C.
* Separtely, hydrate the starch with water, add it to the heat mix slowly until is lump-free.
* When the mix is homogenous, let it cool for 5 min and pour into the mold.
* Let it dry in indirect light and air current for 4 days aprox.
* Unmold when it's dry.

In the first trial we let it cool for 15 min, and decided to rescue what was left in the beaker, as a result we got lumps that gave our sample a weird texture. So, we tried again, and this time we made the mix more homogeneus, also let it cool for only 5 min and didn't scrape what was left on the beaker. The result was better but was harder when dry.

* Hot plate x1
* Digital balance x1
* measure water - measure glicerin- measure gelatin-
* Boil the water
* Add the glycerin and mix slowly
* Add the gelatin little by little while mixing.
* Stir for 20 min over low heat.
* Let it cool for 5 min.
* Pour into the mold.
* Let it dry for 3 days in indirect light and air.

6. Weekly reflection & critical thinking

This week I learned a lot, even though I've worked with biomaterials before, I had to be more independent in the lab, and avoid making the mistakes I've done before, thanks to this, the results were better and I'm really satisfied with the given results.
