Final yr, we made an icy snowman utilizing ice, salt and water. This yr, it’s Santa’s flip. Draw a Santa face on the surface of a tin can, add ice, salt and water and watch as a frosty beard seems.
You should use the identical salt and water science to cool a drink rapidly and make ice cream in a bag!
Frosty Beard for Santa
You’ll want
A clear, empty tin can
Colored pens to embellish
Ice
Salt
Water
The way to make a frosty Santa
Enhance the can to appear to be Santa. We used a mix of sharpies and chalk pens.
Fill the can with small items of ice.
Add a little bit water
Pour in about three tablespoons of salt
Watch because the frost types
If it doesn’t work, maintain including ice and salt. The frost ought to type inside 10 minutes and be strong sufficient to the touch the surface of the can.
Why does frost type on the surface of the can?
The icy water temperature is about 0°C, however for frost to type, the icy combination must be a lot colder, which is why we add salt.
Salt lowers the freezing level of ice, which suggests at 0°C, the ice begins to soften as its freezing level is decrease than zero. To do that, the ice attracts warmth from the environment ( the floor of the tin can ), inflicting water vapour within the air to condense and freeze on the surface of the can.
