Un fluid non-newtonien

On Thursday, students came home with kind of a funny substance. We have been exploring liquids, solids and gases and experimenting with mixing them together. On Thursday, we mixed two liquids together and created a substance that is neither liquid, nor solid, which makes it a un fluid non-newtonien, because it doesn't follow Newton's rules for liquid or solid. Students have promised to only play with this at the kitchen table when parents say it is alright, because it will soak into carpet and upholstery.

Here is the recipe for making le fluid non-newtonien:
1. Dissolve Borax in warm water.
2. Mix white glue and water, half and half.
3. Take equal parts of the Borax solution and the glue solution.
4. Add colour to the glue solution if you wish.
5. While stirring the glue mixture, slowly add the Borax solution.
6. Take the resulting fluid out of the cup and squish it on the table to get rid of excess water.
7. Play with your new non-newtonian fluid!
**Borax as a powder is a mild irritant, so parents/adults should make the Borax solution, and everyone should wash their hands after they are through with the fluid.
