All you need to make your own fake snow at home are some cheap disposable nappies! Tear open the nappies over a large mixing bowl and shake out the small amount of white powder, so that it falls into your bowl. Remove any fluffy bits of nappy padding, then pour in some water, a little at a time, while stirring. You’ll be amazed at how much water the powder can absorb. Watch the spectacular transformation into slushy fake snow! The white powder is sodium polyacrylate, a polymer (a long chain-like molecule) which can absorb 300 times its own weight in water (which is why it’s used in nappies!).
