Going even bigger

When I was shopping I found the perfect mold for casting a balance cushion at Albert Heijn. It's a big hard plastic salad bowl, I'm not sure what kind of plastic.

Ingredients

• 900 ml water

• 100ml dishwasher soap

• 200 grams gelatin

• 120 gram glycerine

The recipe is the same as before but with a slight change. I'll add 100ml of dishwasher soap. I do this because it worked in the bioplastics week and had no fungus. Depending on the soap color, the balance cushion takes on that color, in this case green.

I added the soap later on during cooking.

After it got thicker I poured it into the mold. I poured the leftovers in a deep plate i had lying around to see how that will turn out, out of curiosity. I left next to my open window to dry for two nights to be sure that I can take it out of the molds.

The one in the metal plate dried very fast and hardened as well, it started to warp a bit.

It is nice to see that if you hold it in a certain light you will see a rainbow through the dishwasher soap I added.

The balance cushion came out nice as well. It is the right size and will shrink over time, but it is good for strength and balance exercises.

I left them for the next few days on the same place next to my open window.

During the coaching session with Marjolein I asked the other students if they had some tips for fungus prevention. Desiree told me to flip the piece over time by time. Desiree's tip in combination with the dishwasher soap did the trick.
