Back in the good old days we used to draw and create with chalk.
Don’t seem to see it all that much nowadays but luckily it’s easy to make our own!
WARNING: This experiment is a messy one!
STEP1 - First up half fill your glass with cornflour.
STEP2 - Add water a little at a time to your half glass of cornflour and keep stirring it together. Keep doing this until your cornflour just becomes liquid.
STEP3 - Carefully pour your cornflour liquid into your ice cube tray.
STEP4 - Add food colouring to your ice cubes and mix thoroughly together.
STEP5 - Freeze your slime cubes overnight.
STEP6 - Experiment and play with your Slimy Ice Chalk!
Did you notice how when we mixed our cornflour and water together it wasn’t quite a liquid or a solid?
What we actually made is called a “non-Newtonian fluid”. Not quite a solid or liquid, somewhere in between.
By freezing our Slimy Ice Chalk we changed the properties again and made it into a real solid and by adding food colouring we can have fun playing with our Slimy Ice Chalk.
WARNING: Slimy Ice Chalk is awesome but definitely messy.
