/diy/ - Do It Yourself

look at these badboys
both a ginger ale, but left is orange instead of lime, also made with sugar cane juice and brewed on the fire for some minutes

I thought these plastic bottles would be perfect for my lightly fermented juices experiment, since you can squeeze the air out and it has less of a risk of blowing glass everywhere
however this surprised me, the orange one in just one day puffed out, these bottles are exactly the same, but the pressure on left one was so much that the bottom puffed out higher like that
also this is a custom PET bottle, so I don't think there is so much of a issue of it blowing up, I am however worried a bit, so I opened the cap to vent and let it sit for another day, then put on the fridge
the lime one also puffed out a day later,, also on the fridge now, I'm gonna record it opening up soon

on the matter of density, the lime one was less than 1.020 where the orange was 1.050, and these were fairly juicy limes, and both had about the same amount of sugar cane within, so I'm wondering if we can guess the amount of sugar contained in the mixture by its density, I wonder why it had so much of a difference like that
