If it's soft but cold, that means it's not dense. If it's not dense, that means there's likely a lot of air. Probably almost half.
a 3 gallon pail of their stuff is 15 pounds. Let's turn that into useful measurements.
3 gallons = 11.356 litres
15 pounds = 6.8 kg.
1 ml of water is 1 gram, so if the bucket was full of just water, it would weight nearly double what this bucket weights.
From my time working with the product, I know that Soft-serve is commonly 40% air.
6.8kg is 58.8% of the weight of the ice cream. That's pretty darn close to 60%
Edit: Changed g to gallons to make things less confusing.
That's poor notation on my part.
I'm the dense one, not the ice cream.
