Iceblast! aka best fizzy slushy
The way I see it, it should be possible to recreate the conditions of a slushy machine with the following:
A mixing stick
a bottle to contain the pre-slush
pre-slush(for testing will be juice)
Basicly the motor will poke through the bottle lid stiring the pre-slush as it freezes.
Can anyone offer any advice, precations or adjustments?
