I got this as a funny stocking filler for my girlfriend so we could have a 'white Christmas' despite the rain...
The concept is simple enough. You get two tubes full of a powder that has the consistency of sherbet. You empty half a tube into 80ml of water and stir.
It doesn't create snow by any means. After stirring, the mixture congeals and leaves behind what has the appearance of slushy snow but to the touch is a slightly sticky, rubbery, damp mush of strange consistency.
When you drop the mixture on the floor it does look a bit like snow but that is where the similarity ends. It binds together (as it is quite sticky) but it is just a rubbery mess and bounces off objects if you throw it (so no cheeky snowball fights).
It is a pretty cool experiemental gift but 'Make your own Snow' is extremely far fetched. I appreciated the concept behind it but I think many would be left disappointed if they expected actual snow (which of course wouldn't be possible without freezing or some kind of liquid Nitrogen).
