Create coloured snow like the red or green snow sometimes seen in the Antarctic snow, although that snow is coloured due to algae growing in the snow. Your coloured snow will be due to food colouring. It teaches you all about polymers that absorb water.
Very festive and can used used to make coloured snow whether it is Christmas, Valantines Day or St Patrick’s Day.
Check out the ‘Wacky Science’ video of this experiment and ‘What’s Going On’ series link. They are currently ‘In Production’, so check back soon…..
Wacky Science Ep
What's Going On?
This slime is made up of guar gum thickener. Guar gum is a long chain of sugar units called a polymer. Think of it similar to a string of beads, where each bead represents a sugar unit. In guar gum, there are small braches that come of the long chains every two units. The chemical structure of guar gum is shown below.
When you add the Borax solution, it links the chains togather to make a thick ‘gel’. By adding differet coloured paints, you can create different coloured slime.
