Going bigger

This week I want to create a bigger gelatin based balance cushion. I want to try out two shapes, flat and rounded. For the flat one I use my mold from the housing of the old clock. For the shaped one I use a mixing/salad bowl.

Cooking

Ingredients

Once again I used the Bioplastics Cookbook by Margaret Dunne.

I upscaled the amount:

• 1L water

• 200 grams of gelatin

• 120 grams of glycerine

Left the flat shaped mold and right the rounded - Andrei Motian

In the flat shaped mold I put some transparent foil so it would not leak when I cast.

I mixed everything together in a bigger pan than before and kept stirring until it became one composition and started to thicken. When it thickens i poured it in both molds.

Poured it with a ladle to be safe - Andrei Motian

Drying and testing

After casting in the molds I've let it dry for two nights next to an open window before taking out.

The picture above clearly shows the difference between the flat and the rounded shape. I've tested them by standing on it with my whole weight and doing a short workout.

Testing the rounded shape, I almost fell - Andrei Motian

Conclusion

The rounded shape worked fine and challenging to do exercises and would like to continue with that. The flat shape didn't work out because it functioned more like a mat and you could stand on it as long as you wanted. Another application for the flat shape could be a fitness mat.
