You can also add the same cups or containers you used to create the coloured instant snow or add other tools for scooping and gathering like spoons and bowls. Worried about the instant snow turning a brown or gray colour when it is all mixed together? Try only creating complimentary colours, that is colours that appears close to each other in a rainbow.

Science Behind Super Absorbent Polymers

Instant snow is made from super absorbent polymers. Super absorbent polymers are like tiny sponges that can soak up lots of water! They are made up of special materials that can expand and get really big when they come into contact with water. Just like when you pour water on a sponge, these polymers can soak up water and turn into a squishy gel. These polymers have special abilities because of their unique structure. They have lots of spaces in between their molecules that can hold onto water really tightly, making them super absorbent. That’s why they are often used in things like diapers and even in instant snow to make it feel fluffy and soft. So, next time you see something that can absorb a lot of water, remember that it might have super absorbent polymers inside!

It is best to dispose of your instant snow in the regular trash. Some brands of instant say that you can save it in a resealable container such as ziplock bag.
